Here's a piece of good advice. Before declaring that someone hasn't linked out, double-check. Because, I did:

"In John Gruber’s article today, Title Junk, he gets upset about title tags that produce a bad display or readability situation."

The link is in there in the words "Title Junk." I even specifically called the article out by its name and used anchor text to it. I wanted the link to be next to John's first quote in the story.

"I generally enjoy John Gruber’s writings, but today he’s dishing out SEO advice about HTML title tags. Some of it is bad advice."

Here's a piece of good advice. When you post in response to someone else's posting, have the courtesy to link to them, rather than simply calling them out.
