I was one of the 20 who had to email you but you reacted so quickly I don't think this will hurt much in the long run.

Probably like most people, I had a specific idea for how to use Firesize so when finally taking action it would have been SOP to check back with you again.

In fact, great job in showing agility with the classic startup skill: action -> mistake -> admit/recognize -> improve

Just to provide another explanation. I visited the firesize page and had no idea I was supposed to signup at all to use it. The example provides a way to append any URL to firesize.com, I assumed that was how it was used. What is the advantage of the Heroku signup?
