I have been testing this plugin.
I changed the order to be FB, G+, WP because I feel facebook comments are the most important.
Previously I only had WP comments so it does make the reviews look a bit barer agian and would be great if their was a counter next to each or they were amalgamated into one thread, but that's not my problem.
When I post a facebook comment, it just freezes there. Tested on FB & Chrome
When I refresh the comment is there... any replies I do after that work normally.
With G+ on the second tab, the plugin doesn't load on firefox (it does in chrome)
I've had issues with older browsers on this (like IE8, vom I know, but that's what we are stuck on at work)
This is a post without any comments yet to test if you would like to see it in action.
Any help with this would be greatly appreciated
