Aug. 14: #FollowFriday

For my seventh week of Twitter #FollowFriday recommendations, I thought I’d give a nod to some of my favorite websites on Twitter. This is by no means a comprehensive list, but it focuses on sites where I've gotten to know writers and editors, which is very cool, because they're sites I truly admire.For the uninitiated, I do my #FollowFriday this way because it doesn’t clutter up the Twitter stream too much and I get to explain why I think you should follow folks. I do five recs each week.I’m always looking for more interesting people to add on Twitter, so please recommend at least one person in the comments. Would love to hear who you think is worth my time to follow.So here’s this week’s #FollowFriday recs:• io9: Every sci-fi geek who's not familiar with this site should re-examine his or her sci-fi geek credentials. I love this site, because it mixes an excellent amount of original writing, reviewing and listing with pickups of the best and most important sci-fi news out there - and gives credit where credit's due. Plus, when they did their "10 Mall Massacres With Robots, Freaks and Monsters" post, I noticed they had left out a classic of the genre - Night of the Comet. When I left a comment to that effect, they not only added it in, but also gave me credit for suggesting it. That's class.• PopMech: Yes, Popular Mechanics, the old-school magazine, has a killer website. All Lost fans know to go there the next day for the breakdown on whatever insane brain-twisting scientific concept they've thrown at us. They do lots of killer articles on the latest gadgets, science news and, frankly, cool stuff. Such as: A kit that turns any car into an autonomous robot. What???• EnviroGraffiti: The bio on Environmental Graffiti's Twitter page says "For environmentalists who don't take themselves too seriously." Good description. They post lots of environmentally focused stuff, but also just interesting things in culture and nature. Like this: Amsterdam from Above. I mean, is that cool or what? But even more than that, site founder Chris Ingham Brooke is just a stand-up guy. Very cool, very nice, very smart.• BurbiaCentral: Many of you already know that I write for Burbia - funny (hopefully) personal essays on whatever strikes my fancy. But the site has lots of good writers and tons of funny content. Definitely a taste for the bizarre and funny. You may have been following the saga of the lawn chair war there? This site's for everyone who knows that living in the suburbs doesn't mean you escape the craziness of the city.• LemondropTweets: LemonDrop.com is a really fun website, where girls like me blog on whatever's going on. They're pretty much girl geeks, just like me. And they even have a halfway decent following among the guys, too, mostly of the geek variety. Witness this letter from a fan. Can you feel the love?Anyway, that's it for this week's #FollowFriday recs. Again, please leave your recommendations in the comments for this post; I'd love to hear who you think I should be following.
