welcome!

this is a place where (ideally) you get out what you put in

find yourself some large accounts that post often (and share your interests) and connect with people in the comments

follow hashtags and search for the content you are interested in rather than expecting it to come to you

things can be slow to start, but the bigger you get the more momentum you'll have and cool content you will see by default

there are definitely a lot of millennial book readers here! grunge, art and film!

good luck
