If you add the tag introduceyourself, and introduction to your intro posts, it will get a ton more attention. There are ppl who just watch those tags all day, waiting to welcome new comers, and help new people out.
Usually you can do one general introduction, posted to your own page, showing all the things you plan to bring to Hive. Then when you join a new community, you can do an intro again on the community page. Obviously it's a good way to get more followers, and usually big votes.
The key to success on Hive, is networking, and interacting with others. There a ton of ppl here just to make money, they never talk to anyone, and they usually don't get many votes as a result. If you can contribute to the community, onboard new members, and are just fun to interact with, people will want to support you, and give you big votes to keep you coming back. You're clearly talented man, so I know you have it in you to do great things! You just got to learn a few key things, that will make a huge difference, but that is why I am here to help!
