To be fair, I should point out that the lack of marketing focus on DTrace was somewhat deliberate on our part: we kept any and all marketing folks in the dark until we had satisfied customers. (I've always believed in talking as little as possible about what you're working on until you have cut enough code to back up any claims.) Once we had a bevy of happy customers, our marketing folks gladly talked about it -- but it was never a focus on their part, and the reception of DTrace in the marketplace certainly has nothing to do with their efforts. Anyway. you can imagine the frustration in repeatedly hearing the success of DTrace being attributed to non-existent marketing efforts... ;)
