Free Republic is not a "Web 2.0" site. While the user inteface has been improved and refined over time, it is still essentially the original interface from about 10 years ago. This site was doing what it does long before the idiots in marketing departments dreamed up the term "Web 2.0". The user interface will never be confused with a desktop app. It is not flashy. It is functional and very much a remnant of the 1990's.
From Wikipedia, as one definition of "Web 2.0". It definitely sounds like FR to me. I was referring to the social meme---not a user interface.
