We Don't need an API to Convert External Articles to Steemit, We need an API to convert Steemit posts on websites! - STEEMIT FIRST
What do I mean?
API/Wordpress plugin that when you post on your site it posts on steemit
More important is an API from steemit or plugin that auto-posts what YOU put on steemit into your external websute
WHY?
Make Steemit FIRST - Steemit pays you. This is your platform. Your site is just a copy of your valuable content. You should only produce valuable content and therefore should want to be rewarded for it.
Absolutely Steemit is our platform that pay for our efforts thanks for this kindness in the form of this post @mikeparker
