Monday, I and four others did a DDDBE session on the strategic side of Domain Driven Design.
My talk covered the Ubiquitous Language, and can be found on Slideshare or embedded below. I might end up writing down the content of the talk as well - some images are meaningless without words.
Evaluating feedback, I think the biggest mistake we made was keeping some things too abstract - curse of knowledge at work. If we get the chance to repeat the session, we need to make sure to weave a practical story through our talks to make them stick.
