I love the idea of this, but frankly, this seems like a system that becomes more useful if you use it for a long long time. And for systems like this, I need a guarantee that there won't be "exciting news, we got acquired, and tomorrow all our services are shutting down."

I know that's a bit of a downer take, and maybe I should just not hang out on HN with this attitude, but I really wonder if I'm that alone with this opinion...? It's the same issue I have with roam research, the same issue I had with Mendeley.
