I've been commenting through Disqus for quite some time and, lately, didn't like the way it began to change. Also, as a blogger I was searching for alternative because I want to be in control of my comments, the blog content and everything that Disqus is trying to change. And I think I found it - and don't get this as an ad, because it isn't and feel free to erase the comment, but take a go on GraphComment, because it helps you to stay in control of everything + you're rebuilding your own community in-house and there isn't any of that stuff Disqus does. And if you found some other options, I would like to know and get informed, always in lookout for healthy alternatives, didn't know about heyoya :)
