Opening up things a bit

Having come back from Educon 2.1 I realize that I have to be (far) more collaborative. Not my nature being an introvert but, having tried to blog every year for the past 10 years, I'll try again. Since I can't always talk about CAS, I've opened this up a bit and we'll just look at anything (mathematics U education U technology) that crosses my desk. It'll also help me avoid filling up my colleagues' mailboxes.
