There's this Apple family cousin who was basically shaking her rump at the camera during the song and dance in Apple Family Reunion, and she got kinda popular with the fanartists on Derpibooru :V
@JT: For the life of me I can't remember her fannickname or name :V
It might also have gone better if they didn't waste so much time on the normal parts of the reunion and the flashbacks. AJ didn't even start mildly inconviencing everypone until like halfway through the episode.
Life is simple: it has no nontrivial normal subgroups.
I don't have anything to add to this conversation that hasn't already been said. All I'll say is, AJ is in my top three best ponies.
Tealove is best pony.

I would have hated it if they removed all of the interaction and flashbacks. Those made the episode for me.
Even in Applebuck season, that whole issue came into play only when she was interacting with other ponies, on her own, she would have been working herself to exhaustion, but it wouldn't have created the massive issue it did. And she is far from a "token" anything. She has a very believable, realistic personality, it's just one that doesn't lend itself to zany schemes and comedy on her own.
She's taken over the role of the Tsukkomi from Twi, who has an unexpectedly adorable bookworm Boke vibe :3
AJ can also be a bit of a playful tease, as evidenced a couple of times (trolling Rarity, teasing Spike who was about to accidentally kiss her, making mushy puns at Rarity), and she's also a competitive and compulsive gambler :V
As said though, most of that stuff was most prominantly on display Season One. Nowadays it's toned down with very little new in it's place.
