Rogers Cadenhead explains why moderation of blog comments is not censorship:

After a decade of publishing on the web, I finally reached my fuck-that moment regarding censorship a few months ago. Someone else can carry the First Amendment flag. The speech here isn't free to me -- it's $225 a month plus labor. Telling someone you have a right to free speech on their site is like walking into their house and demanding a ham sandwich.

That exactly correct. I moderate the blogs here, since they are hosted on Cincom hardware. Rogers is paying for his hosting directly, so - as he says - complaints about censorship are like waltzing into a house and demanding a soapbox.

If the government censors you, it's censorship. If you get moderated off on a private blog, it's not.
