The anime still has a solid following, you're just not looking in the right places. Most of the fans of the anime are over at Bulbagarden and Serebii, and both anime sections are very active.
Everyone knows the anime is the same thing over and over, its been like that since Johto started. But people still enjoy the different things that happens, Ash's different travel companions and different Pokemon on the group. Obviously now that the show has nearly 800 total episodes, its pretty ridiculous to try and watch it all, but people still do. So whatever.
