At first I thought this was great, easy to install and looked good on my site.
After a week of tweeting and sending likes to facebook I realized that the URL's being sent are miss formatted and thus dead links.
e.g. www.mydomain.com/page.html was sent as www.mydomain.compage.html.
For some reason the / is omitted ??
So to all those giving this 5 stars please check this as its easy to overlook.
I have no fix at this time ;(
