Ability to filter post by 'text only'

What I mean is, you know how you can browse by new hot, top, rising and all that? Okay, what I'm asking is to incorporate another search category titled 'text only'

So when you sort by text only, it'll only show you text only post, posts that are only contained of text. Although I appreciate pictures and videos I would really love for something like this so I can kind of get to where all the discussion posts are
