Fixed those two rep things.@Dana--As the titles are obsolete, they're no longer searchable in the database, but I've added them in from some old posts. If you do a google search, you may come across a lot of broken links as the information was contained on the old forum system which was removed around Cata. There's a lot of titles, hope you find something neat!
Great guide but I just have one nitpick. In the section about removed titles you said "Either way, here's the removed ones." It would be proper grammar to say "here are" instead of "here's (here is)".
There was a discussion on the WoW forums a few weeks ago on how it's rather surprising that there aren't any achievements for having X amount of titles, like there is for every other collectible thing in the game. I joked that getting 20 titles should grant a Feat of Strength that gives one more title: The Entitled.
It may just be because the article is out of date (or people thought it had been removed at the time) but Hand of A'dal is still available if you have the old quest (the oldold one before the keying was removed from BT and Hyjal) and complete it by getting both the vials. My shaman received the title on 07/04/2012- click here for armory link to the achieve.
