Rate our pivot : PythonAnywhere

We recently posted a 'Rate our Pivot', for Project Dirigible, our Python-based spreadsheet web-application. (http://news.ycombinator.com/item?id=2304691) We received some great responses and excellent advice. The thing that people found the most interesting was the 'effortless cloud supercomputing' aspect, while being least engaged by the spreadsheet-UI. So we trimmed the application to provide something more focused. The result is PythonAnywhere - a interactive Python console in the browser, that runs your code on our servers. http://pythonanywhere.com The user's code runs in a sandbox, to guard against griefers. We're not tied to Python - in a later version, the server-side process could be anything, from Ruby to a Bash shell. Casual use is free, like Dropbox, and we would charge for more resource-intensive services, maybe access to networking, or for access to substantial CPU time or disk space.
