Maemo users, IMHO, are one of three categories:
1. iPhone newbs who thought they were getting the next iPhone when they bought a n900, and spend all their time ranting and causing drama that it's not what they expected.
2. Technical people, working in technical fields who need power and (probably) custom applications. Things like doctors and such(generally in non-us countries). These people ask for coherent solutions, follow directions, and donate/pay for quality applications.
3. Nerds+developers, who most likely work in computer-related fields, probably use at least one unix-based system during their daily work, and when they need a tool, they build it themselves and release it.

Edit:
And the next post couldn't have proved my point any better. :P
I'm sure you guys can tell which category he fits in.
