I was born and raised in Florida, so I've become very familiar with the sonic booms heard when the space shuttle lands. I'm not saying it doesn't make me jump every time it happens, just that I'm used to it.

Space shuttle Discovery landed minutes ago, and as usual, it was preceded by the sonic booms. So what is one supposed to do when you hear this? Twitter it, of course.

I then ran a search to see how many others mentioned the sonic boom, and here are the 6 best tweets I've seen.

#6 - bananakin think I heard the sonic boom. the timing was right and the cat freaked out. I guess it could have been the neighbors, but Im thinking boom

#5 - timrosenblatt I was sitting right next to a large glass window as the sonic boom happened, which made it a lot louder. That was ridiculous. #sonicboom

#4 - wizzlewolf Holy CRAP! My whole house just shook! I thought a car had hit it! It was a sonic boom created by the Space Shuttle landing! LOL

#3 - catdonmit Laughing at myself. Thought I heard thunder, dogs went NUTS, then remembered the shuttle landing! It was just the sonic boom. hehe

#2 - Sorenssibling Just realized the thing that just hit the side of my house was a sonic boom from Discovery coming home.

#1 - NoleNurse just heard the super sonic boom...I think a little poopy came out =/ LoL

Lay post? Yep. I just got a kick out of the reactions.

If you have no idea what a sonic boom is, here's a video of a shuttle landing. The boom in the video doesn't do justice for how loud it actually is in person.

I've been working on a presentation for a meeting in a few weeks, and realized I needed a few new professional looking fonts for my headers. After a few hours of searching - and finding some amazing free work - I was left with about 20 fonts I absolutely loved. I decided it would make a great post, so below, you'll find what I think are the 20 Best free fonts on the net - at least fonts that work for business presentations. Your mileage may vary.

These Twitter mashups probably won't help you with a single thing in your life, but damn they're fun! All of the sites exist for a very specific reason, and do NOT require your Twitter login credentials - you just click the link, sit back, and enjoy. If you like this list sites, tell your friends by RTing this post. If that doesn't make sense to you, you've probably already bailed.

This site is the inspiration for this post. It's AMAZING! Twitmatic finds video links shared on twiteer, and adds them in a video player. I wasted an hour on this site on my first visit. You've been warned!

My second favorite Twitter mashup. This site finds streaming audio feeds and lists them as a playlist. You visit the site, and click play next to a song you want to hear. Perfection!

We've covered video and audio, and this site has you covered with photos. You enter your username, and it will bring you to a page with photos that match your updates. Each photo tells you why it was selected, and it's an interesting way to visualize your tweets.

Twistori has words in the left sidebar, that when clicked, show tweets that have those words in them. I love, hate, think, believe, feel, wish - the choice is yours.

Back to the audio. Wiiizzz is a mashup of twitter and the Hype Machine mp3 blog. The artists you see on wiiizzz are the most popular artists on thehypemachine, and if you click a name, it will bring you to a twitter search with links to streams from that artist. I've noticed, it's usually the same song, but it's still a cool way to find music.

The granddaddy of all twitter mashups. This was the first mashup that came across my radar, and I still visit it from time to time. It takes tweets from the public feed, and shows them on a world map. Pointless? Yes, but a ton of fun if you're bored.

This twitter mashup is fantastic. If you've ever checked out Google Trends, you've probably noticed how difficult it is to find out why a word is trending. Most sites don't index fast enough for google to post accurate stories, but twitter is on top of it. This site shows the google trends words, and has related tweets listed below them.

Like stalking celebrities? This site is for you. It is a collection of celebrities using twitter, and it shows their tweets. You can see the "most talkative," celebrity of the day, and there's a list of celebrities the site is watching in the right sidebar.

Got something to get off your chest, but can't tell anyone? Tell SecretTweet. All posts are anonymous, and most are funny as hell. Apparently someone has a small penis, someone told his girlfriend her ass looked big just so she'd break up with him, and a whole lot more. I'm not sure why more people aren't following @secrettweet because I crack up at almost everyone of the tweets.

A mashup of twitter and delicious. I'm a huge fan of delicious, so this is a natural fit for me. The site shows the most popular links that have been saved to delicious - and they're all fed fram twitter..natch.

Think of tweetmeme as the top everything on twitter. Shows the top blogs, audio, video, and photos. It also lists top users. It's like a 1-stop shop for the best of twitter.

HAHAHA! I love this. It's dumb, and you can't get back the time you waste here, but the concept is simple...they pull tweets with the word "God," or "Jesus" in them, and replace those words with "Science." Hit the link and you'll understand.

If you live by the saying, Misery loves company, this site is just for you. The site pulls tweets of people bitching. That's it. You can rate them tweet, but it seems pointless. Not really sure what the rating does.

Retweets are all the twitter rage these days. This site pulls the most retweeted tweets from set time periods, and displays them. It's a nice way to see what's trending in the RT world.

This should round out the "Pointless" list quite nicely. There's something about the brashness of our favorite 4-letter words showing up in tweets, and cursebird gets that. It streams only tweets with offensive language. Check it out - it's fucking hysterical (see what I did there?).

Know any other great but pointless twitter mashups? We'd love to hear about them in the comments.

From Mashable:

Woody Lewis is a Social Media Strategist and Web Architect. He authors a blog at woodylewis.com about social media strategy for newspapers.

These days, everyone knows that one of the hottest stories any newspaper can cover is that of its own demise. The collapse of print advertising and the downturn in sales, at the news stand and through subscriptions, has led to a frantic search for new ways to monetize content that’s often available online for free.

Social media gives any business an interactive channel to communicate with its current and future customers. For newspapers, that channel can increase the chances of survival in a market where commoditized information has diminished the value of individual brands. Here are ten ways newspapers are using social media to save the industry.

Listropolis' Take:

I haven't picked up a black & white (& red) newspaper in years. It wasn't always easy getting the news I was looking for online, but recently, the big players have stepped things up in Social Media, and now I can get all the headlines pushed to me in Friendfeed or Twitter. I much prefer this method to sitting around searching for news, and am glad to see this social media embrace. Mashable did a great job analyzing the industry's use in this new medium.

From Popular Mechanics:

There's one time of year when it is impossible to get a hotel room in Austin, Texas: South By Southwest, the gargantuan showcase for emerging technology, music, and film. While the festival's music hogs most of the headlines, its film festival (which runs this year March 13–21) has quickly carved out a place for itself as one of the premiere places in the U.S. to debut a new film. This year's Sundance Film Festival took a noticeable turn towards the sci-fi, while the lion's share of SXSW's science and technology-related movies this year are documentaries. Here are the six films at this year's festival that are most likely to pique the interest of sci-tech geeks.

Listropolis' Take

I've never been to SXSW, but I'd love to go. After reading about these movies, I'm pretty sure I'd avoid everyone of them...but the post is interesting.
