Thanks for all the comments.

It's been a couple of months since I wrote the article, so I don't remember all the examples that I used. I know that there have been times for me that using a temp table has improved performance, but if you write an article saying that, a bunch of people will chime in saying don't use temp tables. I think "it depends" on the situation and one tool doesn't solve every problem.

At least for me, I have really liked using CTEs because it makes the query easier to read and I have seen performance improvements depending on the situation.
