Recently added this plugin to a client's website and it's his favorite feature. He loves the way it looks and that he doesn't have mess with anything other than his posts. It has a few very minor quirks, but I have faith those will be fixed and this plugin will just keep getting better. I wish there was a Google+ feed, but maybe that's coming down the road.
No conflicts with my theme (Elegant Themes/Chameleon) or any other plugins in use: W3 Total Cache, BPS, Jetpack.
You need at least 4 posts on each social media page for posts to feed to your site. So if you are setting up a brand new facebook page, or whichever, add your posts before you add the social media page to Tint.
