I like it very much! It looks incredibly neat, very clear to understand and really gives the user an easy way of knowing what is going on at the heart of DDG in terms of new cool developments and additions. and a way of getting those cool things to use them themselves!
However: do you really want to rely on Trello? Now, as a disclaimer, I know nothing about them, but my point is: this is kind of like duck.co being hosted on ZOHO instead of DDG. A lot of people have argued that it would dbe better for DDG to host duck.co on its own servers to maximise self sufficiency and not rely on 3rd parties etc etc. This is somewhat similar: could you feasibly design a page which functions similarly and looks as nice and easy to understand, but which you hosted, thus not relying on 3rd parties? If the answer is yes, then why rely on Trello? If it's too long/difficult/not worth it, then it makes sense to go with Trello, but if not, wouldn't it benefit DDG to host its own stuff itself?
Additionally, to add requests and to manifest one's opinion on pre-existing requests, one needs to sign up to Trello. While it is possible to log in with a google account, maybe it would be better if users didn't have to do this whole signup thing on another website...
Just food for thought, as I said at the beginning, this is still very cool! :)
