steemit.com does now, but I can't believe that some people actual like to use that front-end.
SteemPeak has so many features, great integrated wallet, and the options for sorting your feed, viewing tribes, viewing curation trails, access to all tribes from one UI.. not to mention IMO posts are displayed so much better, and their markdown support and advanced post settings, templates, drafts, schedules posts......
Why go anywhere other than SteemPeak?
Thanks!
Because some frontends like Busy & SteemLeo pays to use their front ends. :)
Substantial payment?
Well, it depends on your aggregate follower MVest. The more you have, the higher is the upvote.
