Can I simply say what a comfort to discover somebody that truly knows what they are discussing on the internet.
You definitely realize how to bring an issue to light and make
it important. More people have to look at this and understand
this side of the story. It’s surprising you’re not more popular since you surely possess the gift.
Thanks, Randi.
I don’t try to be popular. There is a small readership. I mostly write things for my own education and entertainment, and to have a place to put things so I can link them when I get into discussions on other people’s blogs, typically technical. I especially enjoy writing long technical things, but, then, they take a long time to write, develop, and polish.
