I like the post count total. I look at mine in awe and wonder everyday. Plus, contrary to what my buddy mikey1003 said, I used my FT post count as collateral for a bank loan the other day.....
Seriously, I DO like showing post counts as it helps me put statements from posters in perspective. If I'm not familiar with a particular poster, his/her post total gives me an idea how experienced they are with FT. Since we can't "see" or "hear" each other on an IBB such facts as post total, join date, etc. help me understand where a poster is coming from.
And speaking as a moderator, single digit post counts are important as they indicate a newbie who should be welcomed and given an extra degree of help. I might not always notice the join date but a post count of 2 or 3 jumps right out. Plus single digit post counts help us recognize folks who have registered another handle for the sole purpose of trolling. Not that that would ever happen on FlyerTalk......
On another bulletin board I visit from time to time, they have two post count totals: On-Topic and Off-Topic. In the case of FlyerTalk, all posts in airline, hotel and other travel related Forums would be listed as "On-Topic" posts. Any posts in OMNI, Coupon Connection, ORP and other non-travel related Forums would be listed as "Off-Topic" posts. This sort of gives you an idea of how much value a particular poster has contributed to the bulletin board.
