This list no longer says what it is. It's possible you'll also want this list elsewhere, so maybe there should be two linked pages: one for community leaders; one for the team (or the whatever named part thereof which is available for help with pull-requests.)  Or a single page for "Getting Help on GitHub."?

Also, it's not clear in what order, if any, this list is... alphabetical would be cool if it's not in, say, seniority order where the newest additions are added to the end of the list.
