I really liked the concept of your website. It can turn into a successful concept mainly because bitcoin.org doesn't cover the topic of buying/selling Bitcoins. However, you need contributions from other people too. I searched for 'India' and exchanges shown are either no longer operational or are global exchanges which don't provide specific service in Indian Rupee. Current active and popular exchanges like WazirX are not mentioned.
I know it is hard for single person to collect all information because you are not fully aware of the Bitcoin's situation in different countries. That's why it would be better if others contribute to your initiative too.
For current active and trusted Indian exchanges, check the Traders section of this thread:
https://bitcointalk.org/index.php?topic=5177490.0Yes it did take quite a long time to gather all the information for each exchange which I was I started with the bigger, more well known exchanges. I tried my best to locate the best local exchanges in places like Ukraine, Russia, Mexico, Argentina, etc due to there being a lot of resources available on them. I'll check out the thread and research WazirX now.
