I am interested in both. In my example it would rather be Hikamarket I think.
For the time being, shop and social coexist separately on my development site. I don't see a big interest in publishing shop orders in the social profile. I would be more interested in the vendor dashboard data, to create some kind of emulation between vendors, set examples, create networks. I can manually gather performance data (I think...) to create "vendor of the month" or "product of the month" challenges; or pôints to push a particular product for a specific period. I am in the context of a single shop with a network of free lance geographically dispersed face-to-face vendors that need to be emulated and coordinated rather than an e-market of multiple e-shops with one vendor and different products.
I am not set yet; this is why I am looking for what others have done, to see what could fit my needs or give me additionnal ideas, or change my mind...
