subject text Just returned from the <a href=http://c4.rentzsch.com/0/>C4 conference</a> in Chicago. Enjoyed meeting with folks there and seeing the presentations. I think there were about 90 attendees - just big enough to make for a lively community but not so big as to feel lost in a crowd. Many thanks to <a href=http://rentzsch.com/>Jonathan Rentzsch</a> for organizing the event and being an excellent host. <br><br> <a href=http://www.iolanguage.com/docs/talks/>slides from my talk</a> <br><br> I'd welcome any feedback on these or email from folks at C4. password
