One concern I have, though, is reading that Cake is designed primarily for people to follow topics, not people.
There's an implementation issue with that presently, being that all the topics you follow are thrown into your Cake home feed, without any controls/filters. One can't cut the stream down to one or a few of their current interests -- this is rather surprising for an interest-based network, and strikes me as something that needs to be addressed in short order, as it comes close to defeating the whole point.
