Feld Thoughts reports that Feedburner is going to topic specific “networks” (what we’d call channels at b5media) with the aim of better offering advertisers verticals in particular topic areas, as well as giving bloggers the ability to drive traffic to their sites via Feedburner itself (as opposed to just getting extra feed stuff and ads)….interesting move, sort of FM or 9rulesish…..well 9rulesish if 9rules either gets it’s act together and offers advertising options…
