I've frequented a few forums with such points ("Kudos") systems in place in the past. It seems to have no positive effect and is rarely worthwhile. Some forums also have a "thanks" system, whereby you thank someone that provided you with a solution. It just might have a place on tech support forums (though I'm yet to be convinced) but that's about it. Such a points system would be entirely unsuitable for this site and would amount to little more than popularity points with which to massage egos.

For the record: I'm against any kind of points system, post count related merit/rank or anything that causes competitiveness among members, which distorts what the .org is all about (it's certainly not a race nor a competition). I'm also against that which causes cliques and groups to form, such as the social groups we have had since the forum software was updated. I would not miss those at all.
