Are you considering adding a "marketplace" feature? Where you can bid, buy it now, etc. Not in a post anymore, more like a listing.
It's something useful to have as it does get to the point quickly. However looking at this realistically, this is a forum not a Bitcoin classifieds website.
We should be allowed to discuss all posts/threads/items/services freely. One thing I think that I can be done is that we could be able to integrate
a listing within a post. So we could basically have a Poll layout but with a listing in it's place and a section to discuss it underneath.
It's an idea but a listing on it's own would not fit in here.
