A new version is now posted at the usual place (the Mar. 23, 2013 version).   There’s not much to report.  I’ve responded to the advice you’ve given in the previous post, done the bibliography (so in particular, you are free to criticize it), given a little more geometric motivation for completions following the advice of Andrei, and responded to more suggestions sent by email, and by in this year’s Stanford reading group.

Still to do:  As usual, the figures, index, and formatting have not yet been thought about.  (Again:  the bibliography is off this list!  I’ve gotten advice from a number of people on the index, notably Rob Lazarsfeld, and I have at least some idea of how I want to proceed.)  I have a to-do list of precisely 50 items.  (Perhaps in the next posted version, I may have “TODO” appearing in the text indicating where there is still work in progress.)

Questions for you:  it may soon come time to make figures.  Do you have recommendations on how to make pictures?  You might guess my criteria:  I would like to make them look reasonably nice, but they needn’t be super-fancy; and the program should be easy for me to use (I am a moron about these things), and ideally cheap or free.  I’ve used xfig in the past in articles (and the figures currently made), and like it a lot, but I’ve found it imperfect for more complicated figures (with curvy things), and a little primitive for somewhat complicated figures.  I’m remotely considering finding someone who is good at this, and seeing how much they might cost.

Added April 26, 2013:  Charles Staats sent me this beautiful picture of a blow-up.  (I currently haven’t imported it into the file, because for compiling reasons the file goes through dvi, not pdflatex; but don’t bother telling me how to fix this, as I can always ask later if it becomes urgent.)  Caution:  it didn’t view well on my browser; you may want to download it to view it properly.
