I use this every day and love their attention to detail. They are very active improving an already great experience.

@rrhoover I dropped inVision a while ago, so I can't say exactly how they compare at this point. I had poor customer service from them in the early days. Anyone else?

I like the 'tweet to win' pop-up on the tour. Would be interested to hear what the Conversion rate on that is... any one have data on similar experiments?

@munsonbh - how does it compare to Invision (http://invisionapp.com, http://www.producthunt.co/posts/688)? I've been using it recently with @lmjabreu. It's fantastic.
