I find this image representative of the state of cartoons today.
I'll take Dexter's Lab, Powerpuff Girls, and Courage the Cowardly Dog over Adventure Time and Pony's or whatever any day. Avatar is the only cartoon I'd choose to watch from this generation. Don't get me wrong, there are quality cartoons out there, basically most of the DC stuff, but none really stuck with me like they did before. Sara Bellum is still hot to me. Courage still scares the shit out of me. I still own Exo Squad on VHS, and no VHS player. Ren and Stimpy still make me go "WTF am i watching, is this for kids?". And Dexter's "Deedeeeeeeeeeee!" still makes me smile to myself like an idiot. I still watch SM TAS when I get home late from work (only time it airs, apparently), and that was old even when I was watching cartoons as a kid. (21 now)
