Not sure why anybody would want to acquire Campfire? It's an utterly terrible product. If GitHub wanted to added chat collaboration features they'd write them from scratch based upon WebSockets / Socket.IO... not the legacy polling that Campfire does!

GitHub are known to have invested a lot in using Campfire, for example their bot Hubot integrates really well and they use it to manage the majority of their infrastructure.
