You will never be notice by anyone if you didn't take the effort to even let them know your existence to them. Not just by creating Intro Post but rather engaging with the community. It doesn't have to be the whole community, if really busy then reading and commenting to 5 to 6 article per day is already enough. For sure the owner of those 6 article will never ignore you. "Don't post and then run, try to engage more." I learned this on the other platform where I'm a member. Interaction is really important. I mean, doing this is actually fun. And I've doing this for so long and the return is really awesome. I get to meet a lot of awesome people too.
