I've been preparing to try to make an offer for Flickr in the event it goes up for sale (separate from the rest of the web business), organizing it as a benefit corp to be a long term business not to be put up for sale. It shouldn't be an Instagram. Its not a social network. Its a photo site that helps you organize/keep your photos, as well as share them (there's a difference).
Just bidding my time, ear to the ground.
