Communities of blogs?

Can anyone point me towards a community model for “bloggers of a feather” — an umbrella community that sits over a group of bloggers with the same special interest

Here’s the scenario. For the last 9 years I’ve been running a site for saltwater fly fishermen — Reel-Time: The Internet Journal of Saltwater Fly Fishing — which began as an experiment in niche publishing focused on community. The 7,500 + users have flocked around a straight-forward threaded forum system (vBulletin) , generating a hundred postings per day.

There seems to be a good opportunity to introduce a blogging model so each can maintain their own content.

Pointer appreciated.
