Here are 10 #ideasfactory ideas for slogans off the top off my head (I used to be/am an idea machine):

1. Write. Read. Vote. Earn.
2. Power Up Your Potential
3. Grow Your Way
4. If you don't fit, Steemit
5. Connect and Collect
6. Creativity. Funded.
7. Steemit: A Brave New Blockchain
8. Steemit: Because You Are Worth More
9. Learn and Earn
10. Steemit: Where Your Upvote Has Real Value

Some suck. Some are okay. But mostly I needed to get something out so you can build on or ignore. Explainations are availbe or they are open enought to let the potential users fill in their own reasons why they want to check us out.
We'll see...
