I've been on Ello for a month and a week now. Seems like a good time to take stock.
I find the design, interface and atmosphere all quite welcoming. And I don't mind the bugs. I make friends with them until they go away.
The discovery process has been unlike my other SoMe experience. I have 150+ friends on Facebook, mostly IRL contacts from years ago. I'm not terribly active as a poster or reader on Twitter, and barely on Google+ outside of Ingress game-play contacts.
The notebook I've been using for loose notions has a draft for a 'why I don't post here anymore' note to Facebook I wrote late year, left un-posted. In the wake of changes in my life last year I deactivated/reactivated my account a few time for varied reasons, eventually settling on using it for contact purposes primarily.
I've found some amazing people here, followed others based on their content and seen work that I wouldn't have if I wasn't active here. I've also seen others follow me, presumably for interest in engaging content and this is also new and remarkable to me.
There's a greater compulsion for me to post here than other SoMe. I think the simple design more closely puts me in the mind of filling a physical page with ink. The smaller user base also puts me in the mind of BBSing in the early 90s. Perhaps the association renders expression easier for me, feeling less doubtful in sharing my thoughts or work as I was then.
I'm hopeful that I'll continue to enjoy my experience here, and fairly certain that I will. It's been a real eye-opener so far, to say the least. Thanks to @ello and anyone reading as well. My change in outlook since starting here has been one of the best I've found, online or off.
