This might require some UI rework... twitter doesn't reliably set the "following" flag (which is deprecated, anyway) in the user object within a tweet (it's a known issue w/ the API). So, to determine whether or not someone follows you, you need to do another API call, which is a ding against the API limit. So we can't decide whether to render the direct action (i.e., the telephone icon) for every tweet. We might need to get rid of the telephone icon altogether and add a DM button to the user screen instead. Then we can call the friendship API from there.
