Bubbler, announced today, is neat, but why do all these Web 2.0 blogging vendors keep trying to force the storage of content on their own sites? Yes, I understand your business model — $5/month, etc. — but that just doesn’t fly in a Web 2.0, edge-entric world. I may or may not use your tool, and then I will decide — separately — where I will store my content. Forcing the two together demonstrates poor understanding of the world into which you are selling your product — and limits your market unnecessarily.
