As it happens, I'm one of the contributors to the Corante Web Hub as are some of my regular feedreads, such as
Danny Ayres Danny Ayers, Pete Cashmore, Emily Chang, Nancy White (who I met at Seattle Mind Camp) and Robin Good. There are two other Hubs launched too: Media and Marketing. Again, some familiar-to-me blogs are included, such as Smart Mobs and Neville Hobson, but there are some new-to-me blogs too, including Marshall Kirkpatrick and Shel Holtz. Thanks to Francois Gossieaux for thinking of me :-).
Oh, and here's the OPML file for the Web Hub. All good stuff.
