A recent suggested edit to the statistics tag wiki (and excerpt) came up.
The change was to make it explicitly for discussion of statistics relating to activity on the main site (things like my recent question relating to answers per question).
I think having a tag for such a purpose is an excellent idea. As such I (though with some uncertainty) approved the suggested edit. I am still unsure about it, hence this post.
So to my questions:
Is there a need for a statistics tag in the more usual sense?
If that is the case, might a site-statistics tag be better for the purpose of discussion relating to statistics about the main site?
[This is now finalized - the statistics tag was renamed site-statistics via a tag-merge.]
