It's like a search engine not indexing anonymous sites because they don't want to invent use a page rank or some other classification.

The TC change inhibit me for commenting again. I don't like to correlate my FB user with TC, FB is a more private stuff for me and far from my "hacker life".

Also, posting anonymously or with a user not correlated with your real life is something good about Internet. I believe that this is a big mistake from TC.
