Varieties of texts

Texts, blogs, columns, interviews, translations, ... - aren't there too many concepts? The third month I read Habr, but I continue to wander on the site (through RSS it is clearer :)

You can not just leave one type of post - "texts" or "publications" or "open letters" :)? And the categories to set tags or flags, or even statistically (readers) - “it draws on the column” ...

I think it will be easier and more convenient. Now it has turned out even more confusing than the NPJ maize, although he is heaped up too.
