When editing a question, you need to edit at least 6 characters. Typos can often be corrected with one or two characters. Why can we not edit less than six characters?

Your edits require the approval of other members with higher reputation. If you're only changing a few characters this is using up time of these other users for often trivial changes. Once you have more reputation you will be able to make these edits.
