It's so hard for me to fathom how tools like this can be businesses (in the long term). I'm sure it can be done, and similar things have made money in the past, but the privacy part of economics seems so skewed.<p>My data is worth tons to me, nothing at all to greplin, and a little bit to advertisers. How about I give greplin access to as much of it as possible, for some convenience that doesn't depend at all on network effects or even computing resources beyond what I have at home (or in my pocket)? At least when google does this kind of stuff they have other reasons not to leak or sell my data.<p>Good luck to greplin, though! Their success will mainly validate the PIM search space, which will help semweb enthusiasts like me.
Is Greplin mostly screen scraping your sites? I imagine there's a lot of data that people want to search that isn't available via the various APIs.<p>What happens when Facebook tells them it is against the TOS?
