I used to follow Fin but he didn't update much. I'd be willing to follow some other Gaia-employee-type people though. I use Twitter pretty regularly for a lot of things. If I were to follow a developer I would be interested in hearing some Gaia related things as well as some personal life things. I don't want strictly Gaia reports from Gaia Twitterers because, well, that's what Gaia is for now isn't it?
I use it to follow a few of my friends and as an art student, I'd tweet about some really good illustrations to share. But when I'm not doing that, I'd tweet about the smallest things. It didn't really matter if anyone did reply since I know they won't miss it LOL
