I totally agree with you.
Maybe its just me but I feel that the person neither knows anything about Maemo nor Symbian. Its obvious he is totally new to maemo and he himself has declared he has no prior experience with Symbian either.

For me it feels more like a publicity stunt to grab attention. Its like how we used to find joy in compiling small applications like a calculator in C++ back in school. He feels that just by compiling a publicly releaed source code, an OS is born and expects it to work on multiple platforms!
Here, the OP fails to understand that porting an application and porting an OS are two entirely different scenarios.
No offense meant! Its just my humble opinion.

Anyways as usual, I'd never discourage anyone with a good motive. He is doing or trying to do something which I cant do. So I'd always support and encourage in any ways possible.
