#AdventOfCode off to a good start! I don't stay up late to do them (because central time US, work and !young) but still plan to get through them this year. When work doesn't slow me down too much I do.
This year I started a group at work to find other folks interested in #AdventOfCode. Partly to make myself more likely to finish, partly to share the fun, and partly to try to find a community I can raise up and leverage. This isn't the only way to find the other nerds, but it may be the most fun.
