MediumTippr is a quick and easy way to tip writers on Medium using Dwolla. It renders a "Tip This Author" button on the bottom of Medium posts, which uses #Dwolla (connect your account here: http://pound.dwollalabs.com) to render a Twitter tweet box containing how much money you'd like to tip the author. Once you click "Tweet," the author will receive your tip. :) If they aren't on Dwolla, they'll be given an opportunity to register. Find me on Twitter for updates: @brettneese.
