What this blog is

I try to find an effective but scalable category/label for my blogs. I expect my blogs to have many overlapping categories thus too many ad hoc categories will create way too many labels with questionable effectiveness. Therefore I must plan the category/label-ing a bit before commiting myself to a category scheme.

Another problem is my insistment on making labels a consistent characteristic of posts. In other words posts of the same label should have similar topic, depth, tone, prerequisites knowledge, etc. The purpose is obvious, to maximize readers experience such that they can read only what they want and like by reading/feeding from labels they choose.
