That would be great to pioneer Steemit in such a cool way. You should totally do that! I'm sure that could be a big part of your promotional Campaign. :)

Yeah... Better to keep the content new and fresh. Think about what your followers want to see and do updates with links to this post so as to continue building the brand in healthy ways.

Another thing you could do is put together a new redesigned post under the #introduceyourself hashtag. That's going to help a lot I think.

You could also put together your own Roadrunner Racing hashtag so that anyone looking for all of your content can easily search it all in one place.
