Honestly, I imagine recreating the IRC community of CS is never going to happen again -- also there are a bit of rose colored glasses here.
While it was obviously great, the majority of it was just idling in team channels and looking for group/pug/team channels. It was very centralized to IRC and needed then, but better "services" have come along and handle these problems much better, ie: ESEA, reddit, etc. A lot of these communities have come full circle now with discord being popular, and for many games you can find discord servers that emulate some of the CS IRC experiences of the past.
