The 20somethings from ten years ago are now the married 30somethings with kids.

Tangentially related: I was very happy that the zigguratlabs party was family-friendly for the first few hours on Friday night. It's great to see people including the kids. This is the next generation of fandom - be cool to them! This was the first Arisia party my twelve-year-old daughter got to go to, and she had a wonderful time, with a special highlight being when a few toddlers brought her a book and asked her to read to them.
