Hi!
Yes! A lot has changed on the STEEM blockchain.
There are tokens and tribes now. You can get rewarded in STEEM and in the other tokens!
You use TAGS to do this. So, when tagging neoxian you'll receive rewards in their currency 'neoxag'.
You can log into https://steem-engine.com/ using KEYCHAIN to see all the different tokens currently on the STEEM blockchain. There are MANY. This is also where you will CLAIM those token rewards.
A 'tribe' takes it to another level, often offering staking (much like staking your steem for Steem Power) and a website.
If you use https://steempeak.com/ (and you should 😉 ) you can click TRIBES at the top and explore all the different communities (tribes).
Here's a video I did about Steem Tribes for CreativeCoin (another tribe)... I've not actually released any of these officially yet... so... for your eyes first! Hope it helps!
Oh! A Tribe for you!
There's a new tribe called PHOTOSTREEM.
You simply need to tag PHOTO and you'll be rewarded in PHOTO tokens!
