We generally use it if answers have an element of subjectivity or there's no good way of deciding which is best or most definitive, or when we're compiling "big lists" (generally for soft questions), or, as here, if answers coming from different directions are being summarized in another answer. A good example of the latter is here: mathoverflow.net/a/15857/2926 | |

| Jan 26, 2015 at 17:42 | comment | added | Todd Trimble | MikeTeX, I'm going to make this summary CW. It's not good practice to make incremental use of separate MO answers; much better is to edit a single answer. | |
