Recommend Website for Ideas

try Pinterest, Deviantart and creativeMarket

Well it depends! What "IDEAS" are referring to?
As you have mentioned Pinterest and Behance then you can try, I am guessing creative and design ideas.
So you could check these:
- Abduzeedo
- thisiscolossal
- Fubiz.net
- Deviantart
- Creativebloq
- Dribble

gotta say what you're looking for. generally if you look at retro or foundational books of anything you're into it helps with ideas a lot.
