I didn't feel as if it was a ripoff. It didn't even register with me that you were referring to Vimeo until I read the comments. Slightly similar font with a different name altogether shouldn't count as ripoff in my opinion :)
That's just commodification of design; websites tend to exhibit very similar structures, styles, and design elements, so they're eventually bound to coincide at some point.
The logo is nothing more than the product name with a fancy italic font face; that's not even copyrightable. The similarity comes from having names with some matching letters.
