It seems like a cool service, are you charging enough though? I made a site in a similar vein a few years ago but it never really caught on. Maybe we should chat.
Thanks! Yes, we think we need a couple of higher-end plans. The current price points are perfect for learners and low-bandwidth/low-CPU side projects, but something higher-end would probably make it more useful and help our bottom line too :-) Would love to chat, drop me a line at giles@pythonanywhere.com.
