I do this all the time. 4.44 posts per day. It would be much more if I didn't lurk for 9 months before posting anything.
Argh! I hate checking stuff like this. It makes me wonder if I have a life. (I do... I don't know how I squeeze so much time into this place!) I usually don't look at my post count, and when I do, I'm always stunned. I thought I was around 5 per day, based on the last time I looked, but I'm up to 6.50.
2.15 I lurked for a long time before I started posting regularly, and didn't register for even longer. Been around since something like '98.
0.21....i used to be a lurker... though now i've posted 1/day for the last two months.... i probably had 40-50 total posts coming into this year(2005)!
