Maybe, but from my experience I find the more time I spend on browsing through tvtropes in a certain week, the more I overthink my writing and get absolutely fuck all done.

Don't get me wrong, it's worthwhile to understand tropes, but its not going to make you a better writer instantly. And repeated exposure to an attention-sucking site like tv-tropes doesn't help. It'll maybe make you a slower more methodical writer, but that's not necessarily a good thing. You can always fix quite a bit in editing.
