Last night Pownce attempted to launch live to the public, but instead launched FAIL, a tipster tells us in an email with this error message attached. No, this tipster is not Uncov's Ted Dziuba, the Leah Culver-despising hero of all real programmers. We ended all that. Nevertheless, Dziuba's definition of the site remains useful.
In case you forgot, Pownce is a Twitter clone whose added value is the resale of Amazon S3 space. It's written in Python (Django) by someone who rounds floating point numbers using strings, and is only noteworthy by virtue of being cofounded by Kevin Rose of Digg.
