Found http://lookwork.com/ through links on your site. It looks similar to ffffound at a glance, but I'd never heard of either before now.
Would you recommend it?
Lookwork is a very different beast… it is an RSS reader without the pictures. It does, like FFFFOUND, have image bookmarking functions, although at some point down the line we'd like to move that to Pinterest or maybe just Dropbox. But regardless, I personally think it is fantastic for discovery, please give it a try.
As someone new to ffffound, I don't already have an account with favorites. Are there any complete backups of the images somewhere?
