I meant for buyer and seller. I can see repeat sellers appearing here who gradually create a business or relocate one from Craigslist or eBay. Likewise, buyers will develop a reputation as to how they perform the transaction.

Do you mean reputation for the ad-poster? It will be definitely a great feature! We invite visitors and stackers to openly comment and provide feedback on the ad' thread. 

For the post itself there's now the `downzap` that is actually really helpful.

I'm observing right now. I'm anxious to hear buyer/seller descriptions of their transactions, though I know it's a little early for that. I did not carefully read the territory owner's posts, but I assume some sort of informal reputation system will emerge.
