I would advise people to try thinking up solutions that can be implemented now using the tools at hand while considering that communities are coming relatively soon. TBH solutions that require alteration of the development pipeline are not just unlikely to happen, but not a good idea. Steemit.com is a content sharing platform with a filtering mechanism (stake-weighted upvotes), comments, and new features which will be coming more rapidly going forward. If the existing platform can be leveraged we will be able to move that much faster. Unless, of course, people want to build Steem-based apps that solve these problems, in which case we say, "Steem On!" :)
