Just from a quick check of http://en.wikipedia.org/skins-1.5/monobook/main.css?55, removing all the possible white space will reduce it in size from 30882 bytes to 23411
bytes,
saving 7471 bytes (24%). That's a drastic change in size, and if done
would
save a ton of bandwidth (over time).
It's small compared to actual compression, though.

Yes, but it may be a good temporary measure. --Mets501
