SE sites do not allow edits of less than 6 characters. This is counterproductive, and results in the exact problem it is trying to solve: trivial edits.
Because of SE's 6 character minimum edit requirement, when one or two characters really DO need to be changed, the editor must make an additional meaningless edit in order to satisfy SE's arbitrary restriction.
For example, in this QA answer, there was an important mistake in the command that the answerer recommended entering. I tried fix the error by removing a character, but SE would not allow it due to the 6 character requirement. I then had to make another meaningless change (changing the original author's words) in order to satisfy the arbitrary 6 character requirement. This type of edit is often necessary.
So how do we convince SE to remove the 6 character minimum edit requirement?
Update: This is different from the other questions posted on SE Meta. In those questions, it is discussed at length if the limit should be removed, with most people agreeing. But SE chose not to remove the limit, despite their users' pleas. This question is about how to get SE to pay attention to their users and make a beneficial change.
