It does, but it has a lot of the same problems as MS Office, some worse. The scripting/macro system is arcane, proprietary, and only works in the cloud. The files aren't in an easily parseable format. You can export them to OOXML/ODF, but then you're stuck with parsing some ridiculously complex markup. As far as I know the version history is not exportable either.

Also, once I wanted to write some light math equations in a google doc and went hunting for plugins that provide just a bit of TeX-like math functionality. I did find something called "Auto LaTeX Equations", but it didn't really work all that well. It did let me typeset equations, but they came out very pixellated for some reason. I also found "gMath", but couldn't persuade it to render any equations.
