"Memory Alpha:Always fill summary field"@en . . . . . "The text entered in the summary box, up to 200 characters, will appear in italics on the Recent changes page and in the page revision history (see below). You should write a short summary of the changes you have introduced into the article. In addition (or alternatively), the summary field could explain why the change to the article was made, in order to allay the concerns of other contributors (in the case of potentially controversial or confusing edits). Longer explanations should go on the talk pages."@en .

In the day-to-day operations of Memory Alpha, with many people all making changes at various times, it's better to have some summary of the changes rather than no summary at all. The summary can help people decide whether they should go read all of the changes that were made in your edit, or whether it's not important enough. (This would be in addition to the \"minor edit\" feature.) There are a few automatically generated edit summaries, but these are only used in special circumstances."@en . . .
