I was going through old math/sketching graph paper notebooks and didn't want to lose some of the work in them, so I started scanning pages. I took the more comic-y ones and put them up on a server I was testing out, and got a bunch of readers when BoingBoing linked to me. I started drawing more seriously, gained a lot more readers, started selling t-shirts on the site, and am currently shipping t-shirts and drawing this comic full-time. It's immensely fun and I really appreciate y'all's support.
The important lesson here is that some business models absolutely do work for the particular person. I have no idea what number of pageviews you would need to support a full-time t-shirt selling business. I imagine the conversion rate is frighteningly low. But it really is true that you can make a business out of any sufficiently highly-trafficked website with a sticky audience. But you have to match the costs with the revenues.
Lately it seems almost everyone of his articles has been really well thought out and insightful.
Does anyone know if this is what he does fulltime? I assume so seeing as how he said he spent a solid month and a half on the money chart.
