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?
Oh gotcha. Yeah that's mainly for testing, but would be slow to use in practice since it's not behind a CDN. We'll probably start throttling that one, only for use on the homepage, but feel free to signup and use your own account for free.
