Because of constant badgering from loyal isbn.net.in users (Navdeep, Chinmay, Hari, Sandip, Vidyaraj, Kartik, Vivek, Arjun, Leo, Ravi and others), I finally had to dedicate a weekend to fixing up isbn.net.in. However, instead of just fixing up the old code base, I rewrote it to use Compojure instead of the deprecated Noir library, and along the way, I re-did some of the code design to make it more flexible for editing and debugging.
I can't believe people still use the site 3 years after I wrote the first version and put it up, especially with so many comparison shopping sites for India announced in these 3 years which are more functional and cover more categories. But, hey, can't argue with those users :)
Caveats: It's still a work-in-progress, the JSON API, etc. are still not present in this version and more ecommerce stores have to be added, will work on those going forward. And I can use the help if anybody has time, it's open-sourced at https://github.com/swaroopch/isbnnetinclj2.
