Hi
I would love to be able to see what games are being played and being able to watch a game would be awesome.
This would give you something to do while waiting for your mumble required highlander to begin or if you're waiting for a friend you could watch him as (s)he plays.
In CS:GO you can watch your friends competitive matches and watch the big leagues that are happening.
I imagine there could be another page that are called active lobbies and would look similar to the normal lobbies layout but the connect links join the stv.
Ideally it would also show the current scores.
Since there can be some high level players or celebs playing it could be interesting for those who aren't interested in playing but enjoy watching competitive tf2. This also applies to newer players who would like to see the strats and meta and can learn from live games.
The chat would also serve as a comment area for the game that was played.
My last suggestion is to be able to go and view the archive of old lobbies and be able to download and watch the lobby and comment on them.
Thanks for taking the time to read this

(I am also interested in coding and would love to volunteer to help see some of these changes happen)
