I hate that Zawinsky post. At the top, he says "I'm trying to avoid espousing my personal religion here, I just thought it would be good to try and explain the various sects." At the bottom, after thoroughly missing the point about semantic indentation, he says "So go forth and untabify!"
Simply having the editor expand tabs (to whatever people agreed on, usually 4 for C/C++ that I've seen) and save spaces, always, makes life simpler.
EDIT:
See Grandpa Zawinski's post on same: http://www.jwz.org/doc/tabs-vs-spaces.html
