the view number should be more or less correct. One possibility to "view" the post is to click on it. Then the view count increments by 1. Another possibility is: you just click on "show more". This is not considered by counting views.
If you do so, you could have posts read by thousands but the view count still says 0.
If this is the case then the view count is worthless — it is not an indicator of attractiveness anymore.
So we should improve this functionality or get rid of visible view counts at all because they are just missleading.
