Excellent plugin, thanks. I'm running into an issue using it with WPMU Dev's Live Stream Widget plugin.
It's likely an error on that end, but I can't figure out where it's going wrong.
The 'tags' page of global posts is here , and is pulling in posts like a dream.
The problem is, on most of the other pages of the site I have a Live Stream Widget that shows the latest posts and comments (see on here). It thinks that each new post is coming from the indexed 'Stories' site, rather than the author's blog.
