Apparently, StackOverflow says you get paid better for spaces than tabs!

This interpretation of statistical data looks like some sort of post hoc ergo propter hoc fallacy to me.

More experienced and better programmers get better pay, and they surely have seen lots of source code with messed up indentation, so they use spaces.

For instance, one schmock does set tabstop=4 in vi, the next goes WTF?? and is told to set ts=4 to get the intended (indented :-) view, but has set expandtab in their .vimrc, edit, save. The next one pages the file with less(1) and seriously goes WTF.

I use spaces, except where tabs are mandatory. There are a couple of config file formats which absolutely demand tabs.

More chars in the source file, more volume, better pay :-P
