Here's hoping that this effort is where they've been concentrating some of their non-game devs. There have been longstanding issues with Valve-produced UX once you look beyond the in-game aspects. TF2 server list couldn't sort properly on the first update for years, the Steam browser is often dog slow, etc. -- things that are front-and-center pain points for me. A perfect initial release isn't a reasonable goal, but I do hope that they'll be able to polish the out-of-game experience better than they have in the past.
