Google+ finally made me move from Flickr. The integration between Google+ and Picasa is really well done. Now I can upload HD video longer than a minute and a half. I can easily share content with exactly who I want to (without them needing an account anywhere). Before I had to upload family photos to Flickr (world-public, of course, or no one was going to be able to figure out how to see them) then email the album around or post it on Facebook. Now it's all in once place and way easier.
