Welcome, welcome! Looking forward to your contribution to the Steemit community. I'm by no means an expert but from what I've learned, it's very important to get tagging correct as it increases exposure for your posts greatly!

Since this was your first post, "introduceyourself" probably should be the first tag as it's also one of the top categories people search. We're all out there to support each other so you would have gotten more exposure for tagging that. First tag is the main tag and you can have up to 5 tags.

Hopefully that's helpful! Upvoted, followed and resteemed!
