I checked it out and I really wasn't impressed. The UI reminds me a lot of the recently launched Camversity. Each cam initially loads very slowly and at the lowest resolution. The sound is also muted by default which is annoying. The streams were buggy and laggy.
The greatest disappointment however is the experience of going from the cam to the model's clip page. You would imagine they would get that part right since they are primarily a clip site. However, unlike MFC Share which makes the experience less jarring by keeping the cam open while allowing you to browse the model's share items, here it takes you completely away from the cam and just opens the normal clip page. All in all, a pretty disappointing experience. Unless MV manages to nab some exclusive models who can attract a huge audience, I doubt I will bother.
