Every nights I read through the hackernews posts of the day which didn't reach the front page for my newsletter. Every time I click on a medium posts and that I click "previous" the page freeze during 1-2 seconds.
Therefore I have a ban on Medium posts. When medium.com is in the URL it is automatically discarded, unfortunately they offer white label domain so I happen to click on some of those links.
Also I didn't do stats about it, but if you want to blog about something and do it on Medium you have a much lower chance to be featured on HN (not talking about others forum ). Choose wisely. HN is not the center of the world but there are only a few places that can offer 50k visits
