Ello!

Made an ello account but THEY DON'T HAVE TAGS so I can't see me using it much. It has the instant posting style of facebook and twitter if that appeals to you, and I will follow people there if I have to. You have "friends" and "noise" filters (flattering haha) but I don't think you can lock posts. Also you seem to be stuck with a black on white colour scheme.

As I recall it was briefly the New Darling on tumblr for not having Facebook's real names policy, but then the owners did something dodgy like...dealing badly with harassment or something? Personally I'm sticking with dreamwidth and tumblr, with facebook/twitter/ello etc mainly used for grudging replies to those of you without the good taste to prefer the same social networks as me.
