I think it would be a neat feature for hubs to have an optional 'recent updates' panel on the page for BYOND Members. It would basically serve as a list of entries that developers could add to when they make updates to their game, to list what was changed/added. Players for the games could 'Watch' the list for updates, like they do blog posts/etc, and it could notify them via pager of when their watched games receive updates. (They're already notified of when there's a downloadable update on the hub, but it doesn't tell them what's in it, nor does it work for games which are not downloadable.)
You could also put something similar to the medals list on the front page about recent BYOND game updates, which would help those games get a little more noticed without having to resort to spamming the Members blog page.
Just a little idea I had that I wanted to share.
