One of my first go-to web pages, when I open a browser, is the github.com/trending page. I find it fun (in general) to explore and discover the latest in OOS.
On the contrary to the negative sentiment in the blog, I feel GitHub "now" made it much easier to find the relevant contents and repos that I actually care about.
This is a cultural thing more than a remote work thing. At my company we're remote 2-3 days a week but can chat on Skype as needed. Our team (3 people supporting a major app on Android and iOS) talks several times a day to go over things and our team cohesion is good.
