The various "neurodiverse" communities seem to be meshing together more and more. A good chunk of them are autistic, or ADHD dominated interest groups, like FOSS, or various hobbies. It also includes the LGBT+ crowd.

This mixing allows for a lot of cross pollination of ideas. The trans community hears a lot more about FOSS etc than "normals" and so are more likely to get involved. Conversely, the techies have more exposure to alternative lifestyles. Some, who would traditionally do all they could to fit in, now are willing to show off/become who they really are.

The community meshing also helps by its supportive nature. Most NDs have experienced being the outsider to society. The nature of the cause is often very different, but the effects are similar. This makes the community particularly accepting of differences, as well as people experimenting with change.

Basically, all the weirdos got together and realised "Apes together, Strong!". We are now running with it more and more.
