There is a very useful service called TagHistory
(http://taghistory.raifer.tech).

It will show a chart of tag usage over time from late 2008 to 2018.
This helps with 2 of these issues:

1) Comparing this with current numbers from taginfo can show if the
usage of a tag is increasing gradually or if there were huge jumps
from large imports.

2) It also shows how long a tag has been in use, and can compare the
popularity of 2 or more related tags over time.

But there is still no substitute for realistic and helpful wiki
documentation, and for looking at the data directly.
