Don't know if that has changed but I honestly don't want to know, I'd stay away from it if I were you.
I remember many saying the same about the internet when it first became mainstream as well. "What's the use of connecting with other anonymous people? Sounds like ripe for committing crimes. Normal people just talk with each other in person or on the phone"
Any network is prone to go through the same phases of "Just nerds > just nerds and some others who don't have a place > Broader community > Mainstream > Old, left-behind people"
>I'd stay away from it if I were you.
I'd rather recommend anyone on this thread to try it and form an opinion for themselves.
I’d like to poke around. Any chance you bookmarked resources for getting started?
