As I might have said in that original post, it was to add a bit of familiarity to the site. I like the extended profiles with profile photos and cover photos, but that’s it. There is a lot going on with it that helps with using the site, it’s just not totally visible.
Groups can be created, but I’m not sure they are needed, but didn’t want to eliminate that option in case people wanted it. I’m going to look in to disabling the friends thing unless someone thinks we need it.
