users will make irrelevant or useless tags. So the related posts will show based on these tags. For example if a post about difference between home and house has a tag 'difference' in it and another two posts about 'apple and mango' or 'car and bike' also having the same tag 'difference'. Then, even though these all are from different categories they will show up in related posts. In my opinion a general category q2a should not use tags. Only categories are needed. Even if we set it as only categories in general tab, still those tags are hidden there. how to delete those tags?
