I'm a few weeks late to the party, but excellent "Boycott" video. I wish I had watched it sooner, it might have helped me more quickly clarify my own thoughts on the issue. Around the time this video came out I started putting together a web site for folks who have decided not to buy Diablo 3. I wanted something where people could pledge publicly to not buy the game, with the understanding that I would check in with them once a month or so to see if they have stuck to their guns. As people join or drop out, the number of protesters are updated in real time. It's an experiment to see just how strongly people feel about the always-connected single-player games, the lack of mods, the lack of LAN-play, etc., and whether we're all talk or not. Personally, I think that it will be easier and more meaningful to take a stand together. Part of the problem with "personal boycotts" is feeling like you're on your own. You have no way of judging the impact you're making. It's realistic to expect that Blizzard wouldn't notice just one person in isolation "voting with their wallet". But they can't help but notice a bunch of us doing so publicly, and re-committing to our pledge month after month. Anyhow, the site's only just been launched, but I'd still encourage you to check it out :
