well i think the easiest way to make friends on here in general is by following blogs that have similar content or people that you feel like you’d be friends with in general. for example i follow a bunch of people in the lgbtq community and have become friends with a handful of them over the years just by reblogging each other or commenting on their posts, messaging them etc. its kinda like making friends in real life. you make an attempt to talk to them and if they respond well and you find you have common interests, the rest will come naturally. hope that helps!
