If I'm being honest (and maybe others who are saying they don't care about the "fun" side of GH would agree), I have a knee-jerk slightly negative reaction to this side of Github. And it's because I don't really spend my free time contributing to open source projects. When I was younger I worked on more personal projects, and I coded in my free time just to learn new technologies, but I do this less and less now and am quite happy with that. Probably 90%+ of the code I've written in the past 10 years (some of it quite clever and solving some quite interesting problems, if I do say myself) has been for employers. I don't think that makes me a worse future employee than someone who contributes more to open source, and I feel very fulfilled spending my nights and weekends doing other non-programming things.
I'm glad that others have fun with open source and follow along and contribute to projects. It's amazing and it has benefitted me directly with the libraries I use. But as far as the social pressure of needing to be active on Github, for a while that seemed like it might become an expectation for all programmers. And I'm very glad that it seems to be on the decline now.
Edit: and as far as browsing for new libraries and solutions to use in a project, I guess I haven't ever found Github to be very useful for that. There's no easy way to judge the quality of a library, I have come across a lot of things that oversell themselves in the README and are very buggy and incomplete, as well as a lot of things that are maybe used in a small niche in production and very battle hardened but don't currently have a large active community. For me, Twitter and blogs or other discussion forums have been a much higher signal way to find libraries with the reviews of people actually vouching for them as being solid and broadly useful.
