There some reasons prove that, steemit is better than facebook

1. Competitions with prizes
   Daily competions for art, photography, blogs poetry and much more with prizes!! And if you don't like the ones you find, you can always create your own.

2)Dtube
Steemit's own answer to youtube on the blockchain, with rewards using your Steemit account

3)Charity
A great resource for charity, it's so easy to reward deserving posts with a single vote, share the post or comment. Also really easy to send your money (Steem or steem dollars) to the recipitant.

4)No Adverts
No adverts on Steemit, if people try to advertise their posts are generally downvoted.

5)Easy to make money or invest
You can easily make money from your own content, or you easily can buy or sell the crytpocurrency Steem or Steem Dollars. It's free to join, and you can add money if you like, but there is no need to.

6)Community
Most Steemers are positive and great people, and that core is helping to build a great community spirit!

7)You are the stakeholder
In Steemit you have a stake in it's future, and certainly the more active and better quality your posts are, the more you will be rewarded.

8)Control the layout of your posts.
One you get the hang of it, Markdown can create much better formatted and better laid out posts than facebook can.

9)Alternative views.
Steemit creators rewarded any alternative thinkers very well from the outset , which has created a thriving alternative community.

10)Search Engine friendly
More and more now I am getting Steemit results when I do a search in a search engine.
Facebook lacks this and only tends to come up with results if you search for someone's name. Good for getting information out onto the internet, whatever you want to promote.
