Thanks Sophie - great links! I had heard of Ello a while back and after visiting again following reading your post, saw how many more people have joined up. I think if companies announced up front, with reminders, that content posted on their sites was owned by them, I would think less people would in fact sign up. I agree - some social networks are not the best platform to do all your social sharing through, like you suggested (re Facebook). Thanks for the post.
