SmugMug/Phanfare/Flickr are good for photos because they maintain the original full quality of photos that you can retrieve later.
Is there any similar service for videos?
From what I understand SmugMug and other sites chop down your videos with extra compression, and there is no way to ever get back the full quality that you upload.
On the other hand using a straight backup service like crashplan will not allow me to share videos with family.
