Their redesign reminds a lot of google plus, which incidentally was used by many communities because it was convenient and relatively uncluttered.

i dont think people can get excited by this anymore though. Facebook is in a decline trajectory thats going to take a long time. The friends networks have become stale, and people are learning to move to other platforms. Like all other facebook's redesigns, this will create a massive backlash when it launches, but unlike previous times, it will most likely be seen as an excuse to quit the site.
