Makes sense.

I think Rohit probably has some thoughts on this, given his background.

I think this is worthy of starting an examples page.  There's tons of
examples on craigslist and ebay.  With such an "hOffer" microformat, you
could theoretically build a distributed version of those sites, where people
simply publish what they have for sale or what they want, and some spidering
engine matches them up, lets you query them etc.

I wonder how examples for "for sale" vs. "wanted" offers will differ in
terms of their implicit schema.  I'd expect to see a lot of overlap.
