"Steem is a blockchain-based social media platform where anyone can earn rewards."

Isn't this supposed to be "steemit" not steem?

Steemit is the "blockchain-based social media platform where anyone can earn rewards."

And the rewards are in the form of Steem.

The Steem Whitepaper says Steem is "An incentivized, blockchain-based social media platform".

Just want to clarify this.

Steemit is the platform, Steem the blockchain. But the quote for "Steem" is also here: https://steem.io/ (that's the source).

Steemit is a public, transparent amalgam of Facebook and Reddit, just to name a few social networks, that exists on a blockchain where you post and share original content, distributing value to the community and potentially getting paid.

This is the clearest definition in my head now based on my knowledge and experience of it so far and i hope it's helpful :)

yes I also picked up on this after spending a few hours picking up on things. Still made a few wrong turns .

Sub-question: What is the difference between Steem and Steemit?

According to @ned,

Steem == Cryptocurrency and Blockchain

Steemit == Website that pulls data from Steem
