Thanks for this - it's useful to get an idea of how different platforms stack up.
So many of them require an initial investment or ongoing funding to be able to post or vote, which puts me off if I'm then not going to earn anything through it. Hive does it through Resource Credits, and legacy social media does it by selling your details to advertisers, so it feels a bit rough taking a punt on an unknown platform and having to pay to find out if it's going to work. Your post helps save the time and money involved in doing that !
Cool. I'm glad you see the benefit. I agree that pay-to-play schemes have a built in obstacle to overcome. Who wants to "buy in" without any idea of the potential return when there are so many other options?
