Welcome to Steemit!
It can be an amazing place. So much information and some amazing people. If anyone told you that you will get rich here.... don't believe it. Though a few have made some thousands without any investment, most big players invested a lot of their own money to BOOST their performance.

Community is key here. If you don't make friends, it will be near impossible to get people to read your blogs. Even then, it comes very slowly. Look up MSP(Minnow Support Project) and MSP Pal Net on Discord app. You will want to go to @minnowsupport and then join the Discord group.

As for Posts... you have 5 tags you can add. You don't have to use 5. The first one is the one YOU CANNOT edit. So make sure the first is correct. But please don't use tags that don't apply. If I am posting about the pizza that I just ate, I shouldn't tag it as STEEM or CREATIVEWRITING (unless... of course I narrate it as some interesting story full of mermaids and hidden treasure).

You can search tags by typing in: www.steemit.com/created/tagyouwanttosearch like www.steemit.com/created/canada
This will get you started on finding Steemians with similar interests.

Oh... and if you haven't yet... do read through a few of the sections and resources on https://steemit.com/welcome
IT is really helpful!

I am a volunteer here. Mostly I search for people abusing the steemit platform. But I try to greet new users as well and provide some helpful advice. Hopefully I have done that for you!
Take care and goodluck!
