Every now and then I'll read something on HN that tempts me to experiment with the latest hot technology or platform on my little side project.
Then I remind myself it's not just a little side project, it's meant to be a business and I think of an article[1] I read about how Markus built POF with just plain old ASP.NET - it's not ideal, but the important thing is it works and the business success speaks for itself.
