I've been reading a bit today about the new Flickr Foundation, and it does seem interesting. Ultimately, I think I'm still happier hosting my own stuff and copying when appropriate to Wikimedia Commons or the Internet Archive. Sometimes also to Flickr, but not with a sense that the photos will be safe there permanently. Self hosting means not only that I have control and can modify the software as required, but also that I can archive in the ways I see fit (e.g. some stuff is optimised for printing to paper, annually).
