Also, nice use of the word janky.
It is a little cleaner and much closer to the rest of dropbox's site than they could get uservoice. I'll be interested to see if they regret reinventing the wheel and thus having to spend time solving problems uservoice has already solved.
There are obviously some benefits (same login as the main site, they can implement any feature they want, looks more like the rest of dropbox)
This is more like refining an octagon into a wheel without having to pay rights usage.
For example, someone said that the search is really bad. Uservoice probably has invested a fair amount of time into searching liberally enough that it doesn't throw out tickets that do match what the user is asking for.
I'm sure the things I want (propogate folder renames across all users/machines and the ability to change permissions on nested subfolders to make them private/restricted to only certain users) are in there, somewhere, but I couldn't find them no matter what combination of phrases I could think of.
