You go to some users profile & then to his full ranking's list. You then filter his rankings list to have only those with mini-reviews. You get a filtered list - but you have no easy way to read his mini-reviews - you need to go to the movie page and then go through all the other reviews of the movie till you find his. So I was thinking that there should be a way to read a guys mini-reviews if you have filtered his rankings by 'mini-reviews'. But more I think about it - I think it should be a general feature rather than just when you filter by 'mini-reviews'
If you visit the "All movies ranked" page of any other user, any movie with a mini-review by that user could show the same icon used in the "Films in Common" window in the TCI page. And clicking on the quote icon can open a small dialog in the center of the screen (like clicking on the score in your own 'all movies ranked' page does - to allow you to edit your score). The dialog can show the mini-review written by that user for that movie.
