I enjoy Collections as an idea, but despite the pretty interface, everything they've done so far has been buggy or half-assed. First beta launch and not only could no one connect, but they exposed information that would allow anyone to access anyone else's docs. Last launch they add instagram, but no ability to remove accounts, in addition to being very buggy. Now this launch and still buggy (I can't even use our google spreadsheet we use for a test matrix). In addition the beautiful new site broke (for whatever reason) and all the text smashed into on lump of overlapping mess.

You guys have something that is incredibly close to being awesome, but sloppy execution will put a sour taste in everyones mouth and scare them off from each successive release. Spend a little extra time and make sure you're releasing stuff that is bulletproof and your company will grow.
