Blog Types developing


I have ready somewhere here that this plugin is some kind of frame on which, personal developers can built fully-categorized blog lists and call blogs according to categories on main/any page.

Are there any specific coding things, known only for author(s) of this plug-in or will any php-programmer be able to make everything from this plugin?

I mean, are there any specific things, which programmer should take into account while working on categorizing and etc.?
