A couple of quick things: Since I am the dictatorial owner of this site, I'm the one who gets to choose all the topics. It's the only place where I get to exercise unrestrained, absolute and completely unreasonable power, and my wife gave me permission to say that.
Now that my ego has been thoroughly satiated let me tell you that contributing your comments to this blog is really quiet simple. Under each of my posts you will find a 'Comments' link. Click on the link and you will be taken to a comments menu where you leave your name (real or made up) and your comment.
Once you've composed your pithy and appropriate contribution you will close your comment by clicking on 'done'. It then go away until I review it and allow it to be posted.
I am a light-handed reviewer. I don't allow you to cuss like a sailor or post untastefully salacious material. It's okay to criticize and disagree with me so long as you are not disagreeable in doing so. I view my role as a reviewer to be not so much a censor as a moderator.
The most important thing is that comments be interesting rather than inane, pertinent rather than petulant, and where possible, entertaining. And of course, sycophantic, obsequious praise is always acceptable.
If you have any questions, email me at firstname.lastname@example.org.
Now, let the conversations begin.
