Not necessary at all, but I'm interested if there's any way to have a list available of all the posts that we've actually liked.
Not for any reason other than curiosity.
I like this idea as well! Maybe limit it like to the last 20 or so just as the feature that shows your liked posts? +1
I'd also like to see this. Like Arial Ace said, it is in no way a necessity but it would be a nice little feature to have and I am actually kind of curious about what I have "liked" and wouldn't mind having a look over them just because they'd probably put a smile on my face.
