Hey there! I'm one of the founders here at Deekit. I see you brought out the gap in our mobile homepage not having the short summary tagline on the top image. We're actually fixing it to match it with the site you see on the desktop. Totally agree that the twitter-length summary of what the product/service is about should be always the first thing you see quickly.

PS! A collaborative whiteboard in the cloud is exactly what we do - collaborate, draw and discuss ideas on any device and anywhere :)
