Only TWO blogs with self-improvement tag on indiblogger?

I am new to indiblogger. And I was looking for self-improvement blogs. I was surprised when I searched for the tag self-improvement I found only two  blog in the search result. Why is it that there is no self-improvement, personal growth category too?  Earth's greatest treasure lies in human personality and why no category to glorify it? Most of them are logged under inspiration, I understand. Or did I miss out on them?

Am waiting for your replies...
