Welcome on Steemit! Just as most people are saying here..
As Steemit and everything related to it are somewhat different than the typical social media sites and people usually only assume everyone knows around, just leave a comment if there are any questions around here.
There are two typical issues with new users - finding their own audience and finding content they like.
These are basically the biggest issues around, but usually if you find content you like you can more easily find audience of your own and more authors to follow.
Commenting and going through the comments sections for other people interacting with each other are a great way to find people with similar interests. The biggest issue is finding the first people who'se content you truly enjoy.
If you need any tips or recommendations, just let me know :)
