What Happened to the Good Cartoons?

Hey guys, just thought I'd bring up a new idea for my blog. Some of you might think I'm weird when I tell you that I miss some of the old cartoons out there, and I feel bad for the modern cartoons out there plauging kids' minds. What ever happened to the adventures of the Rugrats, or the creativity of the Wild Thornberries? This second grader I know told me that he hates all of the cartoons these days, and that concerns me. Any of you guys remember some of the legendary cartoons out there? I loved so many of them. At least Spongebob is still around, but where the hell are the others? You can't run out of ideas with shows such as the Fairly Odd Parents!
My point is that cartoons were my entire childhood, and now as a sophomore, I can't help but remember some of the cla$sic shows. Here is a list of some of my favorites in no particular order:
Hey Arnold
Fairly Odd Parents
Spongebob
Rugrats
Wild Thornberries
Dragon Ball Z, Dragon Ball
Pokemon (until Johto ruined it)
Dexter's Lab
Power Puff Girls (come on, you all liked them)
Tenchi in Toyko (anyone remember this one?)
Teen Titans
Doug
Ed, Edd, n' Eddy

So yeah there are a bunch I'm forgetting, but I loved cartoons and for quite a time span. I'm not afraid to admit that I continually watched cartoons up until when I turned maybe 13. Now they got rid of all of these great shows and turned Nickelodeon and Cartoon Network into crap. I guess I could always check out Boomerang for some of the shows, but I can't really ever catch any of these shows anymore on T.V. What happened to Toonami? Please tell me they still show that! Or Cartoon Cartoons? I really wouldn't mind seeing these things again for one last time. Cartoons are something I just can't forget. They always gave me a good laugh, and I was always into the shows, as if I were pretty much there. Anyone else wondering where all of these great shows went? Why are the cartoons these day so bad? Damn it! That is all.
Oh and school is a drag.
