BuddyPress.org

2. The Senior Plugins (e.g. Media-Albums, Oembed for Activity Streams, BP SEO, Enhanced Privacy etc.)

These are plugins that almost 65% (or some other number) of sites will end up using but we’re not sure that they will.

BP officially endorses and most likely will use their paid developers to keep these plugins functional.

I’d like to comment that the only developer who gets paid to work on BuddyPress is Andy Peatling. Everyone else contributes; some are consultants or developers or people who create themes, but that’s all on their own back.
