The amount of articles created on our environment is very high. However we know that not all articles are consulted on a regular basis. Some of them are probably never consulted.
At the moment, only views for "external" articles are counted, and they are not for "internal" articles.
Consequently, we can not know if an internal article is regularly viewed or not. On the other side, we can not know if an external articles with 0 views is seen internally or not.
These elements make it really hard to purge the knowledge articles database.
Counting all views, internal and external could help us.
