Thank you for appreciating knowyourgst.
There are many blogs and website which are writing on GST. But KYG has specific focus on GST and this blog was launched with a purpose to help Indian public migrate to GST with ease.
I purchased this domain a long time back and started publishing articles from May 2017.
To answer your point, I do not there is any other blog specific for GST. But there are many other sites where you can find articles on GST.
These 3 are good in quality. I know most of the time cleartax comes on top in google but it is crap and I do not recommen reading its article, these are poorly written and misleading.
