I, as the author, are very interested to know not only the opinions of the users of the site, but also the total number of views of the article.
For some reason, Habr does not issue such statistics, and the search for Habr did not give out even one reference to such a possibility.
You can certainly find a way out - screw the counter with mail.ru or Yandex. Or place in the topic a picture from your site and decide on the number of views of the topic by the number of hits to the picture. However - it would be desirable to see such functionality standard means of a habr.
This can be implemented simply by adding the habracount tag to the functionality, inserting the counter into the right place of the topic - it would be very interesting to see statistics on the number of views and unique views in the topic. Moreover, since the counter can be arranged before and after habracut, it will be possible to view not only the statistics of viewing the text of the topic, but also the statistics of viewing the headers.
