I blog from time to time, a few articles a year, and I don't care how many visitors I have.
When I am curious about something, I read as much materials as I can, and I use the blog as a tool to document my findings and put my thoughts in order. It's rather a last test for me to see if I can make sense, and an opportunity to practice my English.
3 of my articles so far went to this front-page and it was a nice feeling of appreciation. But that's not the point of blogging, internet points don't matter.
