I'll agree with you that there are some really, really annoying bugs (Filevault + Spotlight? Flakey lan sync? Resource forks?) that I'd love to get in and fix, but can't, because the source is closed.

I've run into this with other startups too; getting bugs fixed, or even acknowledged, is like pulling teeth. It's way longer and way harder than it has to be.

Along with APIs, we've been promised selective sync, better permissions, and a whole host of other features with due dates in the 9+ months ago range.

Don't get me wrong, I love Dropbox. Couldn't live without it. I even sent them a resume once along with an expanded bug list I wanted to fix, but never heard back.
