My Steem Experience
Steemit - "Reddit"-like
Every post (like this one) gets you steem tokens
Posts can be (mostly) edited but cannot be deleted (I think)
Your post's first tag cannot be changed after creation so GG for this post
To maximize your payout, it is important to have a good topic and content unless you have a well established reputation or brand
Busy - "Twitter"-like
Busy is on the same steem blockchain - whatever you post there gets on steemit as well
Seems to earn you crypto easily with the "busy" topic
DTube - "YouTube"-like
Most videos on there seem like crap
Haven't tested it, and I'm not sure if I want to try
It's like they combined Reddit, Twitter, and YouTube into one experience!
Taiwainese "Snapchat" on a Blockchain
Lit - "Snapchat"-like
Stories, which disappear after 24 hours, earn you mithril tokens depending on how many times they were viewed and how many likes you accumulate
Yes, these tokens are absolutely useless as well, but I like the gamification of trying to get your next high score story as well
Interesting read: social mining vs bitcoin mining
Summary
Lit is my preferred platform out of the four since no stories seem to be saved on the app.
The mobile app isn't perfect and features are yet limited, but as a user, having a decent app is requirement for any serious online social network. Find me @ jkubo
