I did a little searching about Steemit-like platforms which are already running. The result is that it seems Steemit is the one with most contents right now. But if you want to try other platforms, here are what I found:
1.Decentgo
Like a digital content store, but not many contents right now.
Funny thing: their OP asked me if I want to put my game( already published on Steam) on decentgo. I asked how and why should I do it just to check if she could handle the question. She never replied me.
2.SatoshiPay
Install a plugin and make money from your WordPress contents? Smooth...
3.Tokit
Crowdfund your music/movie/project... alright
4.Streamium
Enter a name and your wallet address and off to go live. So it said.
I didn't try though. Too shy for broadcasting.
5.Snip
This platform look likes a decent one, even with ADs.
- Yours
Create content and get tipped.
7.Bitcoin Megaphone
Create content, pay a few bitcoin to publish and get tipped, hopefully.
