Well, removing items is just making work for yourself, you know. Do you make any use of LR's filtering, so you see only those you want to see?
To give you an example, during my initial run through a folder, the filter is set to Unflagged. So with Caps Lock on, I go through hitting P U or X - keep, unsure, or junk. Ones I really like might get a rating at this time. Every so often I'll use Ctrl or Cmd Backspace to trash all the the X's, and will run through again a couple of times until there are no unflagged pictures. Ratings are
1 OK (hm, I quite like)
2 Show (confident others will like)
3 Good - worth printing
4 Boast - hang on wall!
5 Flaunt - Showcase
In reality, I'm less systematic than I make things sound, but there's never any question of messing around removing images.
