I've always wanted to have a go at "Speakers' Corner". Speakers' Corner is a legendary place in Hyde Park in London where anyone can get up on a box and speak. Whether or not you get someone to listen to you is another thing - but it's a great place for sharing ideas.
So I couldn't resist the opportunity to participate in a "Speakers' Corner" session at the ECIR in London last night. It turned out to be great fun. The audience consisted of information retrieval (IR) experts from around the world and they quickly grasped the idea of trailblazing and the algorithm for optimising trails.
