Forums. I don't really have the attention span for a blog, and you don't get to really meet people with a blog.
When I actually DID have an awesome Blogagotchi going about a year ago (I actually kept up with it!), I was reading one of my reader's blogs and it redirected me to a site called PornTube, not joke. >_>;; It gave my computer a nasty virus too, that took at least a few days for my dad and I to get out of the computer. So I deleted my Blogagotchi, and I refuse to go on Blogagotchi anymore. And I'm still a bit paranoid about sites like LiveJournal and BlogSpot, too.
