He says he got the idea from a short guest-blogging stint on RedState and all the positive feedback there.  In plain black and white, his purpose:

I have created this blog in order to provide Americans with a new meeting place where such opinions and viewpoints might be better shared, discussed, and debated; a place where conservative Americans might really speak truth to power and to one another.  

About an hour and a quarter and 110 comments later, he disabled comments and withdrew a couple posts, too.  Too bad, though.  Some of the comments were among the most direct speak-truth-to-power bons mots I've read.  In the main, they were most definitely NSFW (and would set off the whooping sireens and red bubble lights on TL's profanity filters).  I reproduce a couple of the best, cleaned up in one instance, below:

Aesthetically speaking, this is the most visually bland yet offensive piece of crap to ever find it's way onto a server.

The latter, of course, foreshadowed Tommy's actions later.  

For those interested, someone caught a screen-grab of the posts and 110 comments and has posted them on a new blog, here.  The subtitle to "TomDelayDotCom" is:

Thank you, whomever you are....
