I'm a newfag to this board who's been lurking around admiring some of the cool shit that pops up around here from time to time.

What are some of the most popular or high quality toy brands or genres that people get into (at least on this board)?
What type of toys are easiest for people to get into?
General rules/etiquette that are followed? (Besides the hot glue meme)

There's a hell of a lot of diversity when it comes to what gets posted around here and I'm not familiar with the culture. Just curious.
