Actually, I am lying, this time it is not a silly idea at all.
id software needs to completely remove the obligatory registration for QL and pre-game ads. Many people just randomly stumble upon quakelive.com through some search query or whatever. Generally the main QL page with screenshots and slogans, etc, gives some percentage of visitors just barely sufficient interest to make them click a "Play now" button, but when they see a registration form, 99% of them will just close the page, because it just requires more effort than people are willing to give to some unknown random website. Similarly, when people are forced to see a video ad on some random unknown website, they usually close the page immediately. They don't know yet how good the game is, so they don't have ANY incentive to stay, especially when they know many other websites, familiar to them and proven to be good, but they immediately see that this game demands some actions or some time from a visitor. And choosing between giving effort and time to something unknown and visiting a well proven website/playing well proven game instead is awfully easy.
You need to give user the reward first, and only then ask them to do some effort. If you first require effort, then give a reward, you will just repulse away most of the people.
People should be able to play QL just by clicking a link. It will make a lot of random people actually play the game, and some part of them will become interested enough to stay, thus enlarging the whole QL audience with each day.
