Interesting news from the folks over at FeedLounge: their service, a web-based aggregator along the lines of Bloglines, is going to be a subscription service intially. It’ll be interesting to see how that plays out.
Update: As Alex points out in the comments, there will be a public version at some point after the intial release. Having both has worked rather well for some folks. Flickr comes to mind with its pro accounts, as do Basecamp and Backpack. Good luck!
