Web Feed Storage Container
Seb wants a web feed storage service. Not a bad idea.
I have been thinking about this recently myself...thinking about a service which just acts as a container for feed content and is accessible via some kind of API...could be useful for other developers who want to do cool stuff with the data, but don't want to have to store it all. It doesn't need to be very complex.
Seb rightly points out that Bloglines et al already have this in place though and I suspect that Bloglines will provide exactly the kind of APIs Seb needs in due course.
