Ask HN: What product/service do you want to stay independent?

First off, to avoid semantic distinctions that would detract from the possible answers, I've tried to word this question to allow for a lot of subjectivity. I hope this "pseudo-coded" question works out. Without further ado:

Inspired by this comment [0], I'm interested in your answers to this question: Is there an [independently|privately] owned [product|service|app] that you [use|depend on|really love], and would [prefer|desire|demand] stay [independent|private]?

And the extra credit follow up: Is there some corporation you would trust to take it over? What's your "Plan B" if it gets snapped up?
