Use it all the time. Great tool!

This would be great if it worked on mobile (I.e not desktop optimized)

I agree about the lack of mobile web site, but I broke my resistance and the official iOS app is good (there's an Android one too)

great for coordinating workers and teams in multiple time zones!
