AT THURSDAY'S Web 2.0 event in Dublin, TSSG wouldn't say much about Henry. "What we can say is that it is a system for feeds (RSS, Atom etc.) which aims to make your reading list work as it should from wherever you read it, on any device and with any client". To make the cloud more relevant, Henry needs to be sitting on relevant feeds. If you have a feed others should read, enter your feed's URL and feed Henry. If you don't but you're interested in this idea, you should tell TSSG your name and e-mail address and you'll get more stuff when Henry goes live.
Bonus Link: Paul Watson's Flickr contact list. It contains more names than any Bebo listing I've seen.
