The key concept is to get into the flow of turning over a handful of pages.
This is a good occasion for some PageChurn. It avoids stagnation.
When you get really into it, you'll be HijackingRecentChanges. If done well, this is a good thing for the wiki. It keeps the PageChurn going. The community remembers old issues and takes them up again. Read over the old stuff again, seize opportunities for some real reworking of pages.
When you're doing the SpellCheck thing, hide your changes under the CopyEdit tag. If you change the semantics, change phrases, then you are doing real reworking. Let others know about it. We want PeerReview.
It is a terrible practice to drop "WikiBadge?s" or edit hints all over the site, and it's worse if you hide your little scavenger hunt beneath a veil of MinorEdit. Edit hints never get fixed. Even right now, I am going through and destroying all the references to EditHint for this very reason. For many cases, all I'm doing is replacing the edit hint with CategoryToDo since I figure it's better to have one devil instead of two, but really this is just deferring work until some mystical later. The lethargy of getting around to things "real soon now" is destructive, as cleaning up afterwards is hard. See ReworkingProblems. -- SunirShah
