Ning hasn't updated their development plan in 2 years. The last post was from 2013 I think talking about a new round of bug updates. The original founders left long ago. New owners had interest - but then the new, new owners seem to have none. Rumor is it's totally dead and just keeping the lights on because there are still quite a few communities on there. We're still paying $240 per year there... all images with a .png extension were turned to a lot darker on ning - I was locked out of editing the admin of the site for a week - then it worked - then locked out another week - then locked out 2 weeks. Sometimes sections disappeared - all the photographs just disappeared for like 3 weeks and then poof they were back.
Ning site goes dead end of July. I need to start my "how to join ello and not be scared of the blank white wall you first see" posts. :-) I'm kind of dragging my feet a bit only because I know the iOS app is almost out. And that will help a lot of people. (I'm on a Droid so not me - but it works fine on my droid.)
Google - yes I explained to Ello that going to Google was out because so many people in our community do not like it for various reasons including the privacy issues.
Here's my post to Ello about why I chose Ello over other places for moving rM to: https://ello.co/johnkochnorthrup/post/SJ9HQbju6Xmqx8hpaBDC3g
For me - Ello has all the right attitude and intentions and everyone seems to be making their best efforts to make Ello happen. It's not all there yet - it doesn't all work (read my post you'll see I'm unhappy bandcamp isn't embeddable yet... and private messages... and groups!) But I have faith it's all coming.
I also thought about doing something like Hypnos and just being a forum. But I really loved the aspects of Ning with all of it's media so easy to use... post video's and images and songs right into posts (ello does it a heck of a lot easier than ning ever did).
Anyway - I love it here - won't leave. I love it other places - won't leave. Ello Ambient / Relaxed Machinery is my new "home base" though.
