Greek Blogger Camp - an event featuring Matt Mullenweg, the creator of Wordpress.
Frome their website:
"The time has come for people all around the world to be exposed to the passion and talent Greek people share for social media. There's now the opportunity for bloggers, podcasters and vidcasters from all five continents to get together and discuss what they love the most, on a small beautiful Greek island."
A very smart and well done logo.
