what am i doing here?!

i already have a blog that no one reads. i managed to resist livejournal for the past 2 years or so. this place has been up since, what?, april? and i cave.
i have no idea what i'm doing with this thing. i want to have all comments (anonymous, open id & DW) enabled, but anonymous. i don't know how! i'll want to put something behind a cut at some point, but i don't know how! help!
