I am new to most of these platforms, but Publish0x is blunt and upfront unlike SteemIt in regards to how hard nosed they are on their policies about original content. Plus, it's the only place one of my two start-ups have gotten tips. As far as I'm aware of I have received no tips on any platform, other than Publish0x (which I just joined and published today). However, I must say that Cent has stellar customer support! There was an error on their homepage and I live chatted with them to get signed up on my other start-up (I'm working on two start ups mainly because LeftRelay isn't exactly gaining much traction and I just launched the website in demo mode for my more hopeful start-up). Anyway, that's all I can do in review for now as I'm brand spanking new to most of these platforms, other than the usual Twitter, Facebook, and blah blah blah I'm tired of Facebook's bs too btw.
