^^^ David, for some bizarre reason, many members on here take pride in having a high post count, and posting IBTL just gives them an extra post.
I really have no idea why someone would be proud of being a whore and wasting every ones time (some days I get home from work and have over 200 new post notifications in my email to go through - 90% of them rubbish posts), but therein lies the genesis to your question.
I would rather make a few hundred useful posts than 10,000 useless posts, that is for sure. In fact I think my post count is around 3,000 and I have been on here around 7 years - some people have tripled my post count in 1 year .... sad little men ....
