The best marketing advice I've collected over the years

This is completely off topic, but a co-worker recently asked me for some advice on how to market his new online game. I scoured my delicious bookmarks, found the cream of the crop, and came up with the list below.

I wouldn't recommend trying to plow through these links in a matter of minutes. There is some really meaty stuff here, and you won't get much out of it unless you take some time to digest the advice. On the other hand, most of these provide very specific action items, so you should be able to act on the posts right away. Enough talk, enjoy the fruits of my labor!
