I too have been reading these with interest and the possibility of trying something at some time. Whilst I agree with Bruce that it appears pointless to do when you can buy perfectly good paper in the shops, there is always the sense of pride (and perhaps surprise) in having made something yourself which actually works.
This is the same reason that I tried Caffenol developer last week despite having bottles of Ilfosol and LC29 in the cupboard and the same reason I have built my own guitars and various other items despite the availability of similar items made by more qualified/competent craftsmen.
