I'm adding this as a comment because I wanted to keep my original article concise and to the point (cough, lol, cough, cough): I like being a commentator, but sometimes I find that a blog article can grow out of those comments, as this one did.
If you find an article you like, read the comments. You may find some good stuff there.
On the other hand, when you are commenting , please try to comment in such a way that your comments will add to the value of the article.
I hope my comments are a valuable addition to the posts on which I comment, but it is really up to the writer of the blog post - and the readers thereof - to decide.
