I do that all the time. I haven't yet, today, but I'm sure I will soon. I'm working on some stuff I haven't done in a while. Googling has the extra benefit of helping me to do something that I already know how to do, but more effectively. I can always learn new stuff.
They also mention that people "don't have the time" for open source.
But I do have the time, and the result is a pretty massive portfolio.
It's been kind of amazing, watching it get ignored.
