 Not sure if this has been discussed elsewhere, I could not find it.

 In the Post thumbnail documentation it is stated that "thumb" and "post-
 thumbnail" are both aliases of the "thumbnail" size. But
 {{{
 get_the_post_thumbnail( $id, "thumb" );
 }}}
 and
 {{{
 get_the_post_thumbnail( $id, "thumbnail" );
 }}}
 produce different results. "thumbnail" returns the img tag filled with the
 resized image src and correct width and height attributes, while "thumb"
 returns the img tag with the full image src and cropped with and height
 attributes.

 My take is that the aliases are not really aliases in a lot of the media
 related functions. For example, in wp-includes/media.php line 46 inside
 image_constrain_size_for_editor() only "thumb" is used as alias. Most of
 the times, only "thumbnail" is being used.

 Tested with the latest trunk version coming from the beta tested plugin
 and TwentyTwelve.
