I wanted to try one and see if it worked here:
I think that this can be a good statistic to track as it gives you a feel for how many users actually opened your article. This can help guide authors to work on topics that attract the most views. Upvotes are nice, but I feel that they don't tell the whole story as far as the level of interest your articles generate.
There are also lurkers who don't have accounts but occasionally check out what's going on here. This could help to track them as well.
I found some others that require the webpage address, so I will add those in the comments after I post.
