My site isn't about blogging. It's a blog about tech PR. So it's for that reason that I'm noting the launch of Blogging Planet. It's received some great online PR since its launch, mentioned in a lot of places, most of which I've picked up on separetely, through my RSS aggregator. So to me it's EVERYWHERE!
Blogging Planet seems to be positioning itself a firm that will help customers to use blogs as a PR / marketing / comms tool. The people behind it are established international PR and marketing bloggers, including Neville Hobson. Best of luck with this project!
