The only reason they would scheadule regular patches would be copy/cheat protection.
This is a *good* thing.
If it was just bug patches (are there any more Steam bugs left?) there would be no need to patch regularly.
Also, I seriously doubt any anticheat updates will be documented. That just gives hackers a leg up.
Also, to the person who claimed this was like weekly advertisment: I ask, advertisment for what? Steam? Is someone really going to read Blues News, see that Steam was patched this week (like every week) and decide to buy a Valve game? Huh? Pretty much everyone who reads Blues News knows Steam exists. This won't change with weekly update posts.
