It's very telling that DP's reaction to TBB not linking his terrible content is "you should be linking to my terrible content" and not "how can I improve my content so that he will link to it", or even "actually, my content isn't terrible because....."

Thank you TBB for helping out bloggers when they provide quality content by linking your readers to them, and conversely, thank you for not linking to bloggers when they provide poor content

H/T's are when you are writing about a deal that you found elsewhere. I.E. if Gary is writing about a 100% US Airways promo that he saw on Lucky's site, he'll H/T Lucky

You're not copying DP's content.... you're critiquing it. It's not something that requires (or deserves) a H/T
