Hmm.... I like

1. Witty dialogue. I love it when conversation is exciting rather than just plain old 'Hi, how are you? How's class?'

2. IC internal thoughts. Primarily when it's funny. Serious musings are still ok. But funny internal struggles are... funny... for lack of better synonym.

3. Berty Borr. Always exciting.

4. Things with backstories. It's always fun to trace back plots and storylines.

That's all for now!
