## Mathematicians and writing [closed]

Do many mathematicians write a lot (including expository articles)? Or are there a fair majority of mathematicians that just write papers and don't bother with expository material? Which is better? Do mathematicians lose out if they do not write expository material?

This is quite a vague question and not really focussed on research level mathematics. I suggest that you read the FAQ before asking another such question. – Andrew Stacey Aug 5 2010 at 11:26
To supplement Andrew Stacey's comment, this would make a good blog discussion but as written a terrible MO question. – Theo Johnson-Freyd Aug 5 2010 at 20:13
