I understand that some products are very popular, but I really find the incongruity in downloads and views of some products very strange, is this possible?
I think it is possible if people use more the downloaders integrated in IE Plasma KDE. (AKA PlasmaHotNewStuff)
The downloads via GHNS do seldomly have “pageviews” over html, but are mostly directly downloaded from the “browse” section.
So this is correct, there is no anomaly?
Correct. Most people would search for their plugins, themes and gimmicks in their operating system integrated search modules or even third party software. All of these rather pull info from opendesktop than redirecting here. This should make it understandable why these numbers do not match at all.
