I think what you're doing is super cool and as long as you do indeed provide an easy route to getting the data off the servers then I don't see a problem at all. Is this meant to be a freemium model? Or is it going to be a paid service?

How do you go and use this in a website though? That's another facet of the semantic web that I think needs to be addressed too - content is great but if I have to export it from your servers then stick it into my website, that could get to be a pain.

Is Silk maybe going after a Semantic Cloud sort of model? I think that would not only be tenable but a really smart move. I would use a Semantic Cloud service.
