How come the actual post in now uesrname/password protected? Did the original author intend to use it commercially?

I would assume the site hit its traffic limit. The password protection was then added by the web hosting service. It is accessible again right now.

I assumed same thing. The question is why would they put a traffic limit on it? Seems like it goes against the hope for the website of generating readers... though I guess if he's paying for all the servers himself it makes sense to block at a certain point.

Seems to working again.
