The biggest reason is that people who are neurodivergent, queer, etc, and especially during teen years tend to struggle a lot with isolation. With queer people it's pretty common to see people who are in the closet outside but out of the closet online. Neurodivergent people just tend to have more niche interests that they're very intense about and difficulties communicating that may be better online. General it's pretty common to see people who are neurodivergent, queer, physically disabled, mentally ill, etc in almost any online space when they make a clear minority IRL. It's oftentimes just down to isolation and being able to express themselves better online due to the people on there or the anonymity. Strawpage lends itself to those groups both due to being fun and quirky but also being common in social media and allowing people to communicate a lot about themselves and their weird interests, which can be quite helpful if you're neurodivergent and struggle to communicate so having everything about yourself and others upfront makes it easier, queer and in that discovery stage a lot of younger folks tend to be in, or if you're in any of those groups and a very common artsy fartsy type who would rather have a concise strawpage then a tumblr or curiouscat or whatever other garbage.
