I spend some time, but it is all my time. I don't have the time while at the office for any personal projects. I'm stretching to find the time to keep up with training, trade journals, etc. Since I have a family, house, etc, my personal project time is limited as well. I learn a lot from the other programmers around me, particularly the consultants that we hire for specific projects. They are often younger than I am and more current with technology.
