Lloyd's posted a solution to the disappearing favorites bug I reported on last week. Apparently it was a change on del.icio.us's end that caused the problem. Notes from Lloyd:

There are no negative effects to your favorites on del.icio.us. Unfortunately, the nature of this del.icio.us service bug, requires your manual correction. Manual CorrectionShutdown FlockGo into your profile folderDelete files: flock_fq_default_in.rdf and flock_fq_default_out.rdfRestart Flock

In other news, del.icio.us has finally added privacy to favorites! I know Joshua has his reservations about this feature and that it threatens the sharing focus of the community, but I actually would be willing to wager that more people are going start sharing now that they at least have the option to keep certain things private.
