I think the joke is that both Github and Twitter are famous for being built on Rails (although Twitter just-as-famously required a move off of Rails in order to scale)
There was a great keynote about this at this year's RailsConf
The argument was essentially that if Twitter had instead chosen a language that was more natively inclined toward scalability, they would have necessarily hired 10x as many engineers and they would not have succeeded at building the product that people use to tell each other what bar they are at, simply, which ultimately was the braindead simple thing (that you can probably scale just fine in any language) which drove their success... it wasn't any great technological feat that made Twitter successful, it was pretty much just the "Bro" app that people loved.
(The talk was called "Rails Doesn't Scale" and will be available soon, but RailsConf2018 evidently hasn't posted any of the videos yet.)
