Sort:  

Hmmmm - why more than 8? 🙂

In all seriousness, using lots of tags dilutes the effectiveness of using tags to sort and find content. I believe the main reason people wanted the ability to use more tags is for SE tokens that require the use of tags in order to earn them. In contrast, SMTs will not need to use tags like this at all.

5, 8, then 13? Fibonacci sequence revealed!
