Terming it as a problem with Indian users is racist and hence leads to an analysis that focuses on understanding if Indians destroyed Quora for the rest of the world.

The problem with most online communities is that, as they grow the quality of discussion necessarily goes down.

Today Indians make up a majority of users, that majority could soon be Chinese users or somebody else. Does that make Chinese users the problem? No.
