Blog is perhaps too weak a term; it is far more than that. I'm sorry that it's not intuitive or polished. It really isn't everyone's cup of tea. In a way, it is difficult to navigate because it's huge (much larger than most people would predict). There are currently +12,000 different pages inside the html file. Even the questions of what I think is Good, what is good in the wiki, and what it is good for, are core problems I wrestle with quite a bit inside it. I suggest that if it were to be useful to you, it would be in virtue of your patience and curiosity. I'm not trying to be obscure here, and it's not a mere game. I just don't know how to say it any better. I recommend wandering the entrance.

Just go to ">>" and the "browse hierarchy of tags"

The menu buttons have tool tips.
