It's a two-part question of why and how to avoid that.
Why, especially new people to SharePoint SE, tag the questions so that they include often many if not all of the tags of
As the tags include overlapping and a sort of "either this or either that" options, it's obvious that people are not aware of what the tags mean.
How to avoid that?
Is there a way to improve the tag recommendation with better content understanding? Is it necessary to have all of the above tags as related tags as they are? Are e.g. sharepoint-foundation and sharepoint-enterprise necessary tags to have? Here in Meta we have the at least one of these tags is required -feature - could we utilize it on SharePoint SE too?
The discovering of why should lead to a one solution for how to avoid that. Whether there are other ways to improve in this is something I'd like to discuss about too.
Why I'm asking this is because sometimes the answer is platform/version dependent and it requires an additional comment to find out to which platform/version the answer should be targeted to.
