Hey, I'm going through introduce posts today, and I found yours in the list. Welcome to Steemit!
There are, unfortunately, a lot of bots here. You have some below. Look for their reputations as the first clue. Low reps usually mean they are bots. I wouldn't waste your time feeding or replying to them. Most are scammers.
You can use this webpage to check and see who follows you too:
https://steem.makerwannabe.com/
That will also tell you people who unfollow or mute you. It is a very useful site. I go through that every day looking for quality people to follow back for example.
There's also steemd.com, and that site will give you your stats like voting power, etc. You don't want to burn through all your voting power. Use it wisely from day to day. I try to keep my voting power above 80% for example, and I only upvote worthy stuff.
People with high reps upvoting your stuff raises your reputation. The higher their rep, the more it helps yours. You'll see your rep rise quickly though with the quality content you will have!
Again, welcome, and thanks for joining Steemit.com. We need other quality content producers such as yourself!
Oh, if you ever want to chat, the official chat webpage is steemit.chat. I run a few channels on there, and it is a great way to network and get to know some of the rock stars here!
Edit: I did a rare self upvote to get my reply above the spammers and bots (that's usually acceptable to fellow Steemians etiquette wise).
