Tho, I think if they just asked me to pay what I think it's worth to me, I would pay something. Right away. I'd click the button and pay something, then probably do it again in a couple months.

They should call it, "give Trello a hug", and then I can just hug it with some money whenever it makes me feel happy.

Too sappy? I don't care. I honestly feel like I've found the solution I've always dreamed of with Trello and I could not believe it was free from the day I signed up until now.
