Is it possible to make a SteemIt-like project on NEM?

STEEM is a blockchain, social network, that pays users for theri content. So far, so good.
What’s really great about Steem is SteemIt.com1 - a website that makes the usage of the blockchain as simple as using Facebook (or more like ReadIt).

Some of the unique features of STEEM and STEEMIT.

People whose posts become popular get money for the post. (But they don’t have to put money to make the post.)
People don’t pay transaction fees when adding transactions to the blockchain (operations like post, comment, like, share, send money, follow user, edit own profile, etc…)
public addresses are simple to remember - they are like normal usernames.
Post rewards are distributed piece by piece to many many people, without any transfer fees (except if the fees are hidden…)
