There is no subject matter that is overdone. ... everyone shoots what they want for different reasons.

What is overdone though is mediocre, boring photography.
It's a friggen plague. People with zero skills propping up others with mediocre skills. "Great shot" (yeah except it's pure crap)

Most people just don't hone their skills or show creativity, so what they are showing you is.....meh.

Show me a great squirrel/flowe/baby shot - I'm happy.
Show me something different though. Change your angle.
Make it compostionally interesting and technically good.
