Noob trade question.....

So I am enjoying the game and it has hooked me in, trying not to read too many spoilers and too much of the wiki so I can play through myself.

I seem to have collected a lot of yellow items and they seem more valuable/higher stats than the white and blue gear that I am selling to the in game traders.

Red stuff I have equipped and am using.

The question is as I am only level 24 will anyone want the yellow equipment that I have found or do I just sell that to the in game traders too until I am a higher level?

Thanks in advance.

Unless it's really good, people aren't going to want your low level items. It's too easy to find items to get you through Normal difficulty. Vendor them or stash them to twink other characters you'll be making.
