Utopian is built on the steem blockchain. When you do a contribution to an open-source project by coding / translations / graphics you'll write a post about it on their website.
When something is approved by one of the mods you'll get an upvote from utopian based on the quality of your work.

Youtube can be a bitch. Especially when you're into sampling or doing covers of songs. Censorship also is shit, you could change DNS or use a VPN, that might be interesting to giving you more internet freedom. In the Netherlands is not much censorship :) I'm lucky :D
As a musician you could check out https://dsound.audio/. It's a Soundcloud on the Steem blockchain.
http://dlive.io, a video and live streaming platform on this blockhain, you might have seen it already.

They all post to Steemit, the main thing I find interesting on these platforms is the support by the platforms themselves. Streaming on dlive could get you an upvote by dlive, which can give a lot of support when you care about reward for your time-consuming work.

What I found out about steemit, is that you'll have to really connect with other users by leaving meaningfull comments. That way people will actually be interested in your posts for the time you keep really connecting. When you stop being active on other people's posts, they'll eventually care less about you and stop upvoting you. 😥 This platform requires a lot of "potential follower engagement" since there's no communities/groups/channels.

Maybe make your Steemit more about music and stories about it?
That would be valuable to the musicians here :P Sure thing there's a lot more politics going on here 😂🤣
