It's not because of the language itself. It's because it's implied that the platform my_great_project would be built on is "Chrome, the new C runtime". This is the "platform of the future" and that makes me kinda sad.
EDIT: clarified
That's why I chose to use it as an example and will also use it to present projects in the club.
For example, one project will be to code an HTML5 game, but you can choose to implement it in C or Java. You'll need to be able to understand JavaScript/HTML to learn from the screencasts that will present the project since I will be using JS and HTML5 canvas.
That's just an example, another project idea I have atm is implementing language or compiler.
However, if it really bugs you that much, why not create a Great C Club? The necessity of a good community web site to power it notwithstanding.
There's more to goodness than technical aesthetics -- ubiquity is important and arguably harder to achieve.
Doesn't make 'em any good, though.
