"Don Marti, says Wikipedia, "is a writer and advocate for free and open source software, writing for LinuxWorld and Linux Today." This is an obsolete description. Don has moved on and broadened his scope. He still thinks, he still writes, and what he writes is still worth reading even if it's not necessarily about Linux or Free Software. For instance, he wrote a piece titled Targeted Advertising Considered Harmful, and has written lots more at zgp.org that might interest you. But even just sticking to the ad biz, Don has had enough to say recently that we ended up breaking this video conversation into two parts, with one running today and the other one running tomorrow.
