How is ello better than livejournal.com (lj)? I've been using them for over a decade, and they have never pissed me off the way facebook and google+ always have.
I only stopped using it actively because everybody moved to facebook. One of the things I like most about it is it supports automatically pulling data from it to other sites, and pulling data from other sites to it, via RSS (a standard that exists exactly for that purpose). I've always felt like not having that feature was an indication of an evil attempt to lock you in. Ello, facebook, and google+ don't have it.
