I don't get this strange virtue of new-age geeks. If you said "Make For the Fun of It", i'd get that; making can sure be fun. But making things for no point whatsoever, other than to keep yourself busy? At least with knitting you eventually get practical use out of what you spent time on.
I have a shelf of unfinished projects and directories full of thousands of lines of unfinished code. In retrospect I wish I had spent my time flying a kite.
The point is that if you are only looking to have fun once the going gets hard you'll just stop and shelve the project. On the other hand, if your goal is to make something ie if you are Making For the Sake of Making (tm) you'll be more likely to actually cross the thresholds of difficulty at which you learn significant lessons.
At times you don't need to learn something which you probably might not implement ever, but its good to know it anyway along the way.
I don't really like how its framed 'Make for the sake of making' but I think that was the idea.
You should complete the good projects and release them.
Maybe it should be "Make and share."
