The blogosphere is an interesting place. I happen to host the blogs of two friends of mine under my domain. A few time ago, one of them found a new, interesting blog and left a comment on it. The blogger on that site returned the visit, and found our mutual friend, also leaving a comment in his blog. Some time later, I followed the links in the comments, and found that the blog my friend had linked to was part of a collective. More interesting, one of the blogs in that collective belonged to a former coworker. It’s a really small world.
