It's spelled "SteemIt," and actually, it's been around for over a year and a half, so it's not "brand new" by a long shot.

Otherwise, these are some good tips.

As far as content, the most popular stuff on SteemIt is about cryptocurrency and apps built for the SteemIt platform.

I would also advise against putting a ton of time into every single piece of content you create. Of course, that's not to say that you should not work hard and put out great content, but as of late, SteemIt has become a bit more of a popularity contest than a platform for great content.

I certainly agree you should emulate what successful Steemians are doing, but you should not copy them and try to write about stuff you don't know much about.

Good job on this post!
