I have just subscribed to technorati.com to get my Link Cosmos as an RSS feed. Interesting service, but I still have to understand if it's worth $10 per year.

Anyway, I think that the real news here is that for the very first time I'm paying to get an RSS feed into my aggregator. Here's an interesting excercise: go trough the feeds you are currently subscribed to, how many would you pay for?
