shouldn't blogrolling.com be able to write little utility where it would go through your blogroll and grab RSS feeds from sites that have them which you could then import into the aggregator of your choice somehow?
I have the usual suspects in my bloglines aggregator thingy. I don't want them but I can't find all the lesser knowns in my blogroll without going through them one at a time and finding their feeds, can I? Or searching for them in the aggregator?
Hello, that's a hell of a lot of work.
I think I'll just keep surfing my blogroll and forget the aggregator thing.
