I've been a tab user since forever. The biggest issue with using spaces is not how much you indent, it's the bad pattern of aligning stuff vertically beyond a simple N-level indent. Using spaces to align stuff on multiple lines causes multiple problems. Any changes will affect surrounding lines. This adds busy-work to realign everything, especially if you're not using a fancy editor plugin to do it. It also makes for bigger diffs, which add pointless noise when reading diffs, and potentially unneccessary merge/rebase conflicts. It's also assuming that the text is displayed in a monospaced font. A (very rare) few of us like to code with good looking proportianally spaced fonts instead of awkwardly spaced typewriter fonts.
