Comments: love 'em. Shows someone's reading.
I have the authority to allow a comment to be posted. And I will and do welcome them. Except in three situations.
The first is gratuitous graphic language and abuse. Been there. Done that. Don't need to revisit. No how. No where.
The second is spam.
And the third is where someone is using the comments section as a means to try to sell something. So if you post a comment that has an internet address for the purpose of commerce, I'm not going to go there. Sorry. But those are the rules. And arbitrary and capricious as they are, they are mine.
