"The original project (Enhanced Steam) was created by Jason Shackles (
jshackles). Unfortunately, he has announced its end of life, so IsThereAnyDeal team has decided to pick it up and continue to enhance Steam for you.
The original extension has been live for years, and Jason did a tremendous job with it. However, as with any project of this size and years of support, it needed a little bit of cleanup. Therefore, we have completely rebuilt it from the ground up, aiming to provide as many of the original features as possible, while adding new ones down the line."
Hope jshackles got a decent payday from it, but from that it sounds like he just let them have it.
