This plugin regularly fails completely and must be deactivated on blogs.
Currently experiencing the second blackout in less than 6 months. Googling current error in the plugin "Please check/recheck/enter your Google Analytics Profile ID" now has 528 000 hits!
Furthermore it's very hard to communicate with the author, as well as posting on his "blog"/support thread. You don't get a confirmation that your post is queued, nor do you get notified of updates in the thread. This lack of notification also affects the author as he is not notified, and is left in the dark until he decides to check. Disqus would resolve all this in the blink of an eye, but he doesn't care.
This is really frustrating, as the plugin is the best there is when it's working.
Perhaps it should be donated to someone who is more capable?
