But who would cite a comment, then change its meaning by changing the image and/or the excerpt text? I don't think we have to worry about that, considering something like this is so easy to catch and would be considered vandalism.

Comments can be linked to directly, however, the comment has to not be farther than 1 "more comments" button, and the comment has to be one of four newest comments in that thread.
