how do i dreamwidth (2.0 i think)

insert pleading emoji and hands pointing at each other bc im too lazy to figure out if i can insert that here easily

i would love to use DW more often because i think i like the idea of this style of interaction a lot and i've never really participated in a space/platform/community like that! however due to [see above] i actually have no idea how to like.... do that..... i feel like to me, i think of it as kind of like ao3? you post stuff and maybe people respond. but like. how do you find new people? how much chatting and interacting is encouraged and/or desired on posts? what kind of stuff is reasonable for me to post? i realize that these are all subjective and no one will have coherent answers but i'm feeling very adrift for not having expectations here haha
