I make Supreme Commander casts of great games, if you like watching Supreme Commander or want to learn a bit from some analysis of top-level gameplay then why not come check out my channel!
Here are a selection of decent videos to give you an idea of what I do:
Here is my first tutorial which is a great intro for new players:
Cool, yeah, I am aware of your channel, zaphod; good work!
For those reading this looking for more in-depth analysis casts, I cannot recommend more highly of TA4Life; check him out as well: http://www.youtube.com/user/praisegugleourmaster
TA4Life casts a lot of 4v4 Seton's matches, as well as 1v1 tournaments, and has casted many games of TLO (yes, the Starcraft 2 player).
Never get discouraged, just let your nerdy flourish.
