Hi everyone,
I interpreted the introduceyourself tag to mean that your post should be you, an individual, introducing themselves (duh?)
So like, I'd say "Hi, I'm and here are various things about me, etc etc".
But I think some people just view it as the "newbie" tag where those new to Steemit hang out. I've seen websites and companies introducing themselves. Some think that any first post should go there, whether you are actually introducing yourself or not. And I'm sure many just consider it a way to gain extra attention to their posts.
Any other interpretations?
