Luckily with a community like FAKKU around, I am capable of finding out about new anime that may or may not catch my interest. Manga is kinda a different thing. I just sorta sit there and whatever name sounds interesting I will take a look into. Mangatoushoukan had (and still has) a genius system where at the top of the page will be an ad for a manga hosted on the site and this helped direct my interest to certain manga's.
I personally know that there are still a couple idea's in manga and anime I want explored (A slice of life-ish anime about vampires) but as a whole, Japan is just a country filled with highly imaginative people who's ideas have reached out and influenced people over seas and is also influenced by the people over seas as well.
To quote Einstein here,
Albert Einstein wrote...
“Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand."
