Golf Social Networking Sites

Ok, so I saw an advertisement on PGATour.com for a social networking site called Stracka.com. That was a new one for me, so I went to take a look. I have also seen 19thhole.com as a golf social networking site. It basically is a copy of MySpace, but golf specific. Are there any others out there that I am missing? I want to get a feel for the whole golf social networking world. Or, are these two the MySpace and Facebook of golf?

ADD on 4/1/08:

I was emailed about this post by another blogger named Josh Morgan. He actually did a post concerning Stracka. They're employing a technique of promoting their product that is known as paid reviews. In essence, they are soliciting space on blogs for posts that are "reviews" of Stracka in a positive light. This is done to increase their Web search optimalization - placement on Google, basically - and get positive "reviews." It is not an unprecedented practice, but it is a bit shady considering that the product does seem to be pretty solid. What's worse, though, is that it appears that Stracka employees were creating fake accounts and posing as users of the site to add comments to the sponsored posts that pimp out Stracka. Shady.

Your thoughts?
