The site held up fairly well to a barrage of traffic after its launch, which made me wonder what makes it tick. Lead developer Leah Culver was kind enough to answer some questions via email. Pownce is built on a variation of the LAMP stack: Debian Linux, Apache, MySQL, and Python. But the site uses a number of less mainstream technologies (e.g., Django, Perlbal, and Amazon S3) to speed up development, improve performance, and reduce costs.
