The hottest sites (in and out of beta) in the webosphere, as measured by the number of bookmarks at del.icio.us added within the last 7 days. Currently more than 18,000 sites are tracked, including the 7,800 betas listed at the MoMB. This list will be updated weekly.

Note: Yahoo started to limit access to the API of delicious, so I currently can't update the lists.
