Hi, today I got the talk to propose a name and a logo for the event. After the discussion about naming of events and some additional thoughts, the proposal is simply:
It is a usual practice in conferences and events to have a name detached from location, year, edition, etc. Now the MediaWiki Hackathon is in Amsterdam, in the future it might be again there or somewhere else, but it will be our beloved MediaWiki Hackathon anyway.
Back to Amsterdam, the web page and other materials could use a standard formula like:
Amsterdam 24–26 May 2013
The logo proposed is also tied to the "MediaWiki Hackathon" and detached from a specific location, year or edition. It can be used in the future as such, unless we want to evolve it. There is also a version without text.
The logo combines the sunflower (a reference to the technologies powering Wikimedia projects) inside the circle made out of 3 segments (representing the Wikimedia community). It follows the Wikimedia visual identity guidelines and you can find the sources at media:MediaWiki Hackathon UNOFFICIAL DRAFT.svg.
