Oliver Cohen has recently launched Fmeme, which lists the “Hottest Links on Facebook.” It’s like Techmeme, but just for popular links shared on Facebook.
Results can be sorted by photos, links, or videos, or by a list of several topical channels. Users must log in via Facebook Connect to submit content.
Fmeme is not associated with Facebook. “Fmeme is not in association or partnership with Facebook. Fmeme is not sponsored or endorsed by Facebook. This site was only developed to show the great things that can be accomplished using the Facebook API and its social plug-ins. We are aiming at best practices and do not store passwords.” as found on fmeme.
