Honestly not because there a lot of sites like it and steem is unique where you can get rewards just for bloging and being 'active'
Dont get me wrong im not on steemit for rewards either when i make blogs i really try to do it best i can so community can stay 'healthy' and spam free
Thanks for your comment, I only found out about steemit through researching it and what it was used for as you do when youre looking for reason to invest in other CC and altcoins on the market and not just blindly.
