Number of topic views could be useful for some sites (e.g. with articles or reviews).
A good example is esoTalk:http://esotalk.org/forum/1170-fat-free-indeed
There is a topic view counter... I just don't know what's the right place to show it
I love esoTalk btw... well, some of it
esoTalk and Flarum are good examples of advantages having only one developer. Many, many fresh ideas and a great overall product.
I was always looking for something like that written in Python or Ruby on Rails. And now there is Spirit.
Near to the topic title? Top right corner? For me it can be even in the page footer.
