I’m testing it right now. Works fine so far.
There’s just one thing that could be better: Google+ integration. Right now I have to use Buffer in addition to Post Intelligence to post to Google+ and Twitter at the same time. I get it though, Google+ isn’t quite as popular these days. It is however quite a powerful SEO tool. Especially now that I signed up for the PostWithGoogle beta. I’m doing a lot of networking via Google+.
