Developers who use spaces make more money than those who use tabs
The reason I use tabs is pretty simple.  It's faster to move around only using the keyboard.  It's also faster if I'm changing code that requires reformatting.  Finally, when another developer looks at the code, their IDE will render the tabs as whatever its set up for, 2 spaces, 4 spaces, etc.  In other words, it adds flexibility.Brace yourself: I use two spaces after the end of sentences too. [1]  I am quite the rebel.Modern IDE's (Sublime Text) let you easily convert spaces to tabs (or vice versa) and intention length of existing code.
