I like the interface. I agree that "The easiest way to share your entire content" is an awkward sentence. Also, I would suggest making the "Blog + Photostream + Videostream" bit more prominent on the homepage because it's probably the fastest way to explain what the site is, yet it's not the first thing I see on the welcome page by a long shot. Nitpicking here, but I also don't really like how the "red" in Sprred is red in the logo. The site is very clean but the logo could be better.

Seems like a cool service.
