Ken:
I appreciate you taking the time to leave a comment, I really do. I also appreciate the fact that you used a mild title and saved your unkind comments for the body of your message.
I know from years of experience, as I would expect that you do too, that it is extremely difficult to please all of the people all of the time. Its just not possible. When writing technical articles sometimes you go for the higher end of the technical scale and other times you shoot for the middle of the road. That way you are assured to at least please some of the people some of the time. I think that is fair.
That being said, I was a little surprised by the rest of your comment. The title of the article/gallery was pretty straightforward: "Seven Ways to Open Windows Task Manager." I mean, based on that title, what other "useful tips or insights" were you expecting?
As I mentioned above, some articles/galleries shoot for the middle of the road and I would hope that folks on the higher end of the technical scale, such as yourself, would read the title and say to themselves "I already know those tricks, so Im not going to read this article" and then move on to some other higher-end articles. With that I mind I can only come to the conclusion that the "complete waste of time" was entirely your fault. I am sure that there are plenty of other readers who will find value in some, if not all, of these tips.
