Some people are just posters, and some are lurkers.
I seem to post often for short periods of time, "post spurts" if you will, and then lurk for awhile.  It's taken me 7 1/2 years to accumulate my ~1100 posts.  Others seem to get on and post about everything and nothing.  To each his own, I guess.
I'm sure some of you will remember the guy (I don't remember his username), who had member number 10ish, and just made his first post a couple years ago.
