If you are spamming my comments you get deleted. If you are, in general, not being a good online citizen, you will be deleted.
If you have something to say that is polite and respectful, and I don't agree with it, it stays. But if you cross the line with me...
The delete button is wonderful thing, and I use it with great joy when required.
The picture is of a wild turket making a break for it when it was discovered by me and my camera.... for some reason it seemed appropriate today when I scanned through my comment section of the blog.
