I frequently come across old questions/answers with small errors/mistakes (Spelling, formatting, moved link etc.) but I'm always hesitant since they get bumped to the front page for no real reason except trivial formatting. Should there be an option to edit a question/answer without bumping the post back to the front page?
Similar note, is editing answers/questions to fix outdated external links a valid edit reason? Most of the pages can be found with a quick site-specific Google.
