I like how my articles are published by many sites within their categories (such as tech) which makes it easy for me know where they're being read from! And also that you can see what other people have said about your article too - this feedback helps make sure any mistakes or typos get fixed before publishing so users don't needlessly click 'publish' with incorrect information/typo's etc out there when reading them! Nothing at all really but maybe more detailed info would be nice? It could help newbies not feel overwhelmed :) We've been able use our own keywords & tags instead using some pre-made ones because we wanted something very specific to us rather than trying find another service who had those already set up ready made :).
