I used to go and add tags to peoples posts if they only used one tag (currently there are two questions tagged only "bearded dragons" which that tag has only 23 people following it, and I would go add it to "reptiles" and then another tag depending on their question). Recently ive noticed that stack exchange requires a 6 character change in the body of the post in order to edit it. I have also found out through experimentation that if you add a few spaces at the end you circumvent that without a noticeable change to the question and you can still add the tags.
So do you guys think this is a useful thing to do? Do you think we should circumvent the character limit just to change the tags or do you think it doesn't matter?
