Scientific American is on twitter (@sciam) and wrote up a quick list of science people they follow on twitter including Carl Zimmer aka @carlzimmer, evolutionary biologist Jonathan Eisen aka @phylogenomics, and science writer Rebecca Skloot aka @RebeccaSkloot amongst others.
If you are unfamiliar with twitter, it's an online service that, in it own words, "is a service for friends, family, and co–workers to communicate and stay connected through the exchange of quick, frequent answers to one simple question: What are you doing?" It's a great way to keep in touch and up to date with real time news, peers at a conference, or people you've never met who are interested in the same stuff you are, like science!
This site (microbeworld.org) even has it's own twitter feed (@MicrobeWorld) where you'll find constant updates about what is going on here at the site as well as great conversations amongst other science enthusiasts such as @JATetro, @Microblogology, and @SelectAgent just to name a few.
If you're already on twitter, post your twitter name here to add to the list of great science twitters above. If you haven't yet joined twitter, give it a shot and join the growing conversation about science, keep up to date with science news, and meet new people by adding your name here or following one of the great twitters listed here.
See ya in the twitterverse!
