Ha! Ditto! My friend brought her DVDs to my house when she came up to stay with me for a few days, and she was determined to get me hooked on DW. Well, it wasn't hard. And the first thing I did was fall head over heels for DT.

I'm about to start watching S4 online, since the DVD isn't out yet (I have DVD sets for S1-3 though), but I already spoiled myself and watched Journey's End on YouTube :P
