We are a open site listing tech events around Scotland. Open means anyone can add an event, like a wiki. We can import data from suitable open sources, and most importantly we have many Open Data feeds. Our data is reused many times by many different people and sites.
We are about to celebrate our 4th birthday, and are the main listings site in Scotland. There is a great community around, and we are proud to be part of that (we are based in Edinburgh). Our software is Open Source to!
Give me a shout if any questions, Thanks, James
