Is there a page listing all the features that Cyanogenmod provides over Android?
The page with the section "So what is the difference between Android and CyanogenMod" talks about how Cyanogenmod comes to be created after each Android release but doesn't describe the actual features.
Compared to others, the point of CM is precisely not to add too many features and provide a close to stock experience. It's not that useful if you have a Nexus device, but otherwise you can get (1) an Android version without all the clutter of HTC, Samsung or others (2) a recent Android version even if the device is old and unsupported.
