I 100% agree that the trending page is useless, I never use it. I also think that searching with multiple tags is a fantastic idea! I also think that Steemit should add some type of language recognition feature, or require one of the tags to specify the language. Don't get me wrong, I love that we've become such a diverse community but when I go to welcome newbies in the #intoduceyourself tag, I can't understand over half the posts. Again, I'm not suggesting this as a method of segregation, but if I only wanted to see posts in a particular language, I should have the ability to search for that language tag and potentially other tags together.
Just my two cents...
