Welcome to Steem.
You are in for an exciting ride....Hang on!

As I was told when I first started out a couple weeks ago you should use 5 tags.

intodyceyourself intoduce-yourself introduce introducemyself introduction
Something like above.

Also if you go into the settings there is a place where you can say something about yourself.
So when you click on someones name you can see the blurb.
Click on my name and you will see what I mean.

Good Luck!
