I have received this plugin as an addon along with Hello Dolly and Akismet.
So I assume it has come from WordPress highly recommended, which I would naturally consider. Reputations are what is fueling good rank. however, the Author has not had a blogpost since 2009 on the site promoting this pluggin. No plugin updates in 2 years and from what I could see no support help in well over a year, maybe longer. I would normally never consider any pluggin that had this track record. Could WordPress not take this over if they feel it is important? It may well be a great pluggin, but I have set guidelines for myself suggested to me by many well reputed blog posts promoting WordPress.
