Cool. You will meet and make many new friends here.

The best way to do so is to glance through the various feeds (People you follow (Under the Steemit Beta icon), Trending, New, Hot, Promoted), and find posts that interest you. There are many trivial posts that really have little content of any value, but among that stream, you will find plenty of good and even great posts.

When you find such posts, UPVOTE those you like, COMMENT on them, and then maybe REPLY to any replies that you get. Soon, you will see the number of your followers increase.

Also, below are a few basic points of advice re posting on Steemit.

1. Longer posts are more lucrative than short posts. If you make a post of 20–30 paragraphs, it's more likely to earn rewards.
2. Include some photos, images or graphs, to complement the text.
3. Make sure the text and photos are formatted properly, so that your post looks attractive and appealing.

Hope this helps for now. Good luck, and Full Steem Ahead!
