How should we write tag wikis for broad or general tags? Such as
Yes, absolutely. Tag excerpts are not meant to simply define what the word of a tag means. They are meant to describe when and how those tags should be used on this site specifically.
Since this site is not generically about either algorithms OR history, it becomes especially important to describe how those subjects fit in the context of this site.
I see some potentially misleading tags like [python], [engine], and [storage]. Adding a bit of context about where they should be used can help avoid the occasional off-topic question that may not fit this site at all.
