In the tool the modals could really use a X button to close the modal, the 2 or 3 seconds i second guessed where to click each time was annoying. It would be cool to discover if asana had some of these features all of a sudden but i think putting so many features front and center is going to hurt your adoption. Slack for instances can be easily underused as simply a chat application, later on the tech guy shows up and starts dropping in chat bots and cool helpers and what not. The relationship stuff is pretty cool i hope i dig more into this stuff later.
Also are you guys planning on expanding the signup options beyond google/microsoft? it was easy for me to signup just curious how much of a roadblock that is to the rest of the internet.
