I got an idea of Xteem.

Xteem will be a crypto-media Xteem, based on Ethereum, Nxt blockchain or other POS blockchain. Xteem has several functions:
1. erasable blockchain, in which article or reply in a transaction can be deleted for copyright problem;
2. TA software for analyze stock, coin market;
3. many parameters of Xteem are changeable by contracts, so don’t need to change source code.

How a user earn money?
Not like Steem, which reward the writers by Steem dollar.  just to like reddit, weibo, webchat...
a)   an user gets money by others’ tipping;
b)   answer other user’s question;
c)   write a article which reader pays when read;
d)   trade others’ fund and get fee.
