Dr. Adorable's Ask-Along Blog. You'll find lots of illustrations of the timid pony doing her best to be adorable (spoiler: she succeeds) and some funny comics detailing her adventures.
If you fall head over heels, there's some pretty pony-tastic (I can't help that I used that word, watching My Little Pony has affected my brain) wallpaper you can download:
AND! WeLoveFine has a t-shirt design featuring the Dr. here. Maybe I own it.
This makes other people happy, right?
