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.<p>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.<p>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?
