A big part of finding success here will be honestly just thoughtfully commenting on stuff folks put out there. It'll create a network of users who go 'oh I know that name!' and you'll find support and growth even if they and you don't necessarily share blogging interests.
Some folks think that bare-bones comment-spam is the same, as I'm sure you've seen or will see soon, and it's not. Real replies with real thoughts are a cheat-code here.
Best of luck!
The main thing that I've noticed is that those who seem to do the best here are authentic and opinionated. There are a lot of posts and comments that are careful, or summarize a topic factually, but not emotionally. But people who are actually being themselves are the ones with a following and who find success.
