I'm no advocate of rapid change for its own sake. I mostly do POSIX systems programming, and the churn of web development frameworks does not appeal to me at all. However, I still want to at least aspire to learn new stuff and stay informed about what other people in my field are doing. Every technology has an expiration date, and as I get older and more ensconced at work, I've been getting paranoid about getting too comfortable. Specifically, I'm paranoid that I know relatively little about web development, period. I am not some twentysomething hipster web guy, I'm a weird middle-aged Unix guy. Although I've rarely pushed myself to learn about something because I felt like I had to- I'm just interested in software and have always enjoyed learning about it. I don't have to force myself to do it, and I probably wouldn't be productive if I did. The only thing that really matters is doing whatever makes you happy. If it has pragmatic side effects, great, but if it doesn't make you happy then it's not worth doing.
