hehe, I sometimes don't log in either, because I don't want to be 'pulled into the black hole of spw'
(where time disappears magically and you end up answering posts for hours even though you just wanted to 'take a peek'...) I only log in if I really want to answer someone or check up on PMs etc.
But yeah I was surprised by the number too.. hmm? (never looked at it before really..)
I wonder if they also count 'robots' or 'spiders' crawling the nets - for example Google robot to index things, so they can be found by Google etc. When I was on another tinier forum, it was really funny - sometimes there were just a few people and more bots than people.. (Google, Yahoo, etc) But I don't know if these are counted here too, or not?
I sometimes read forums before joining too... One can sometimes lose track of all the forums and passwords etc. After joining some forums and not posting then, I kinda understand the people who just read too - though it would be nice if you'd join in and post something too, yeah!
Maybe they are also friends or relatives of people with sa or such, trying to figure out some things..
