I do re-read, but mostly by accident - that is that I will go to amend or correct something and sometimes I have to read a few paragraphs to find what I'm looking for. It's not something that I would go back to do otherwise, because I tend to see flaws, rather than anything else (even the bits I think are OK seem to always be overshadowed by the flaws around them).

I don't tend to cringe when I have to re-read though, so I guess that's progress...?
