Best of luck, many commenters on HN seem to really undervalue the "it just works" aspect of things. It looks nice, seems to do something I am really anxious for help with, and not much more. I can see myself paying for this (potentially :) - need to get it working first!).
One perhaps funny anecdote for you - I am recently an engineer-turned-manager and this type of unified task/meeting management is one of the growth areas I've had to focus on most over the last year. Thought I'd let you in on a potential niche^2 market that might be a good fit for a blog post or something similar down the road.
