Don't be afraid to remove a stub tag if you think there's enough information on an article or if you know the source really well and know there's very little information to be had.
The Category:Stubs and its various sub-categories are full of articles with stub tags on them. Especially notable are the Category:Character stubs which has 1000+ articles tagged with {{character stub}} and Category:Real world stubs and its sub-categories also have over 1000 articles tagged with the {{real world stub}}. Some of these might not need the stub tag on them, the same goes for the others in the Stubs category.
It is of course encouraged that if you find an article lacking then add relevant stub tag to it. This helps with maintenance of the wiki.
But on the flip-side also keep in mind removing stubs. --Tangerineduel / talk 13:04, October 24, 2012 (UTC)
