The easiest way to directly support a musician is to buy copies of their album (or other merchandise) when you see them on tour. They get a larger cut then they would if you bought it in other retail outlets, and you get the satisfaction of making their artistic pursuit a bit more sustainable.
There hasn't really been a corresponding option for people who want to support a particular videoblogging project, at least until today when Have Money Will Vlog launched. Now, potential patrons can pledge support for projects that they want to see created. You can pledge using a credit card or PayPal and you're only charged if the target goal is reached.
The first project pitch was so awesome I couldn't resist clicking on the pledge button. Of course the fact that it's for a Human Dog production didn't hurt. In September 2004 I suggested that Human Dog was the first great content producer for videoblogging (when I also though that Adam Curry was the new Ted Nugent), and while I'm willing to concede whatever the point I was trying to make about the Nuge, I'm still confident that Chris Weagle is worth putting a couple bucks toward. COME ON PEOPLE. There will always be a Garrett Lambert, but do you really want there to not be an American King?
