No, I think it kind of goes against what we're trying to do here - if a list like that became popular, it would supercharge the growth of certain communities
There's a lot of people pushing for that because it would make the site a straight Reddit replacement, but the promise here is a lot like the original promise of Reddit - give users a single place they can go to access a bunch of small forums
If someone makes a community for that purpose or a community wants to draw in all the Reddit refugees, I have no problem with that, but I think the growth would be healthier if people find them organically rather than putting a centralized list somewhere
Sites will start to pull in a community if any of the members on that instance sub to it and there's talk of adding the ability for communities to band together in multis
