It has always struck me that philosophy is not a subject that has made any real progress. A lot of elaborate constructs of when we perceive certain things to be piles and so forth seem to be problems that can be dealt with (eventually) by sciences such as psychology and neurology. Why waste time constructing elaborate theories that are not scientifically provable? Things like inconsistencies in how people act may be a result of people just not being perfectly logical creatures. Why waste so much time pondering questions where 1. progress is hard to judge 2. the resulting ideas do not really change the world in any significant manner.

I share Richard Heck's sentiments on this matter, and I would add that there is an additional sense in which a lot of philosophy is 'before science'. I'm thinking primarily about epistemology and metaphysics in the philosophy of science, where we are trying to work out how science works and what attitude we ought to take towards scientific claims. Insofar as one takes science seriously, it is natural also to take seriously these 'before' questions, however incomplete and inconclusive our answers to them may be.

Should we philosophize about philosophy? Why?

Here is one reason. A central task of philosophy is to figure out how our knowledge-seeking activities work and what they achieve. That is epistemology and it is, for example, a big part of the philosophy of science. So if you think that philosophy is in the knowledge-seeking business, then it is natural to be interested also in how that activity works and what it achieves.
