thanks for getting in touch, aris…and good luck with the project. i’m interested to see what you find. i’ve been active on medium for less than a year. ali mese’s early work helped me understand some of the whys and hows behind the platform (this is a good place to start: https://medium.com/swlh/how-i-got-6-2-million-pageviews-and-144-920-followers-d4d3fa440802#.j0h3e9ln0).
in terms of the lighthouse, three things: 1). the audience a writer brings to medium is everything (as in, if they have a following already on one of the social media sites, especially facebook, that often translates to eyeballs and recommends), 2). if a piece scores a ‘medium staff’ recommend, or already has one when it is acquired by a publication, it helps a great deal, and 3). if a piece gets the attention of medium folks with big medium-followings this drives traffic (like an ev williams or someone).
best of luck, aris!
