OK, at first this seemed pretty dumb. What does it mean, exactly, to "join" a blog? Isn't it more meaningful to show support by adding the feed to google reader, leaving a comment, or showing up as a visitor in the MyBlogLog (even though the latter is such a tongue twister it always makes me think of Bob Loblaw's Law Blog)?
But tonight I caught the first glimpse of some of the value. A Friendfeed post sent me over to Mashable to read an article called How To Get the Most Out of Friendfeed. While there I noticed a different post about Google Friend Connect and started reading it. In the comments someone noted they had gotten GFC running on their blog for tech volunteers, CodeKindness. This is definitely a topic that interests me so I "joined". Only two other people had joined. I decided to check them out. One had also "joined" Bwana's blog, and that reminded me that I wanted to do the same. How do I know Bwana? From Friendfeed, of course. Nothing earth shattering, but it was a nice little full circle of, well, connection and connecting. The bonus was that Bwana had a great article on Google Friend Connect himself. One that really delves into both the implementation and potential value for bloggers and communities.
