One thing that complicates your situation is that your customers are not the users; your customers are the e-commerce sites you sell to-- the end-users are their customers. This makes "Have you talked to your users?" a bit more complicated. My pivot suggestion: "e-commerce mixed with social" is a great niche, but I don't think your MVP has nailed it, yet. I'd move away from the emphasis on real-time, and think, rather, about "How can I leverage social networks to support the sales process?" Note that one of the tough nuts to crack is the chicken-egg problem; the more content that's produced by end-users, the more valuable the service is-- but you need to prime the pump somehow. As I mentioned (via email), I'd love to talk to you in more detail about possible ways to do this in my particular sub-niche (online bookstores), but I imagine that a lot of the stuff can generalize.
