Being a homebrewer has definitely spoiled me.

[Jorlem]

When I heard 'homebrew', I didn't actually think of RPGs.  I thought of software for hacked phones/tablets/game systems.
Is that worth more geek points, or less?

I'd say more since I associate the word with open source programming and not RPGs at all.  Really, what dose homebrew have to do with RPGs?

Fan rewrites or expansions of rpg systems, mainly. Over on the White Wolf Exalted forum, I've seen fan written subsystems, mechanics rewrites, and even a whole new Exalt type.  You can also google Genius: The Transgression for another good example.
