Right now I can tell you I didn't do much to market except designed a good product, a good presentation, and took advantage of the ridiculous amounts of traffic going through the Facebook events mentioned in OP. No magic or silver bullet here. Will go into more detail with a blog post soon. Madebyloren.com

I really love the landing page and envy you your skills in that regard. Also, some of your remarks suggest that you have substantial background with some aspects of this, like shipping t-shirts. So it sounds like you capitalized on an area that came fairly easily to you due to experience, positioning, and other factors.

Looking forward to your blog post. I very much want to work a few miracles and leave my current situation.

Thank you for sharing. For me, as a non-programmer, this is really much more inspiring (as in something I could aspire to) than the posts about some program someone wrote in x amount of time.

You should link madebyloren.com from the footer of your t-shirt page - the benefit to your blog because of a link from a viral page will outlast the t-shirt sales. :)

Thought about it, but decided against it. First, there is absolutely no content on my blog as of right now, so no reason to return ever. Second, I don't think general demographic that visits snowday2011.com would necessarily benefit or appreciate the content that will eventually be on my blog (startups, programming, design, hacking). Third, I've planned on posting a detailed account of the project (including hits, rough financials, etc) since inception, and I don't know if I want this information to be readily available to every Tom, Dick, and Harry who happens to stroll through the site.

You're thinking users, I'm thinking search engines.

The people who are visiting & buying the tee probably wouldn't even notice the link.
