So here are my top 10 websites for finding gifs and images:

10. http://reddit.com/r/animaladvice

9. http://9gag.com/

8. http://pinterest.com/popular/

7. http://gramfeed.com/

6. http://cinemagr.am/trending

5. http://mlkshk.com/popular

4. http://reddit.com/r/funny/

3. http://flickr.com/explore/interesting/7days/

2. http://reddit.com/r/gifs

1. http://imgur.com/gallery

I've never found a good site for what's popular or trending on Tumblr, Instagram, Google+, Facebook, or Twitter.

Anyone have any suggestions?
