A la TripAdvisor, I think we should add a "Did you find this post useful?" box to each post. For each "yes" vote, we can add 1 post to that poster's post count; for each "no" vote, we can deduct 1 post. We can even add incentives, such as for every 25 votes, the poster receives/loses 1000 bonus posts.

If we see a poster with 1,000,000+ posts, we know we are in the presence of a FlyerTalk Master and should read carefully. If a poster has a really low count, or, heaven forbid, a NEGATIVE post count, we can ignore him altogether. Then each anniversary we can have a "post count" party in which we celebrate the posters with the most impressive post counts amid much fanfare and unrestrained frivolity. The following day, with our migraines at their peak, we can excommunicate all posters with negative post counts amid much hissing and booing. And pyrotechnics.

I propose we implement this new system on the post following this one.
