I just realized you can look through your "Profile view" to see what posts have gotten "+1".. My most Favorited ones are usually of boobs or funny gifs.
Find your name somewhere. Click on your name. That takes you to your profile page, which has "stuff" about you, including your posts, your rep, your avatar, etc. In the boxes on the left, click "Reputation" and it'll show you your reppy stuff.
