I think I may have an answer as to why photos I uploaded to Flickr recently have been getting anywhere from 50 to over 100 views very soon after I uploaded them. All the pictures whose view counts have gotten bumped up like that have one thing in common: I geotagged them. (i.e. I added Flickr tags containing their coordinates and also the special "geotagged" tag) So, somewhere out on the net, there's probably a program downloading all the geotagged photos from Flickr either via RSS or the Flickr API. What's it doing? Could it be the latest implementation of Geobloggers? Who knows? And why is it downloading each picture so many times? The mystery only deepens.
Incidentally, Flickr's view counts are a little screwy. I noticed that if I comment on a photo instead of just clicking on it, I'll raise its view count by anywhere from 2 to 5 views.
I did some counting of my own:
I have 6 photos with over 200 views each, totaling 2,078 views.
I have 74 photos with view counts between 100 and 200: 74 * 100 = 7,400 views.
I have 328 photos with view counts between 50 and 100: 328 * 50 = 16,400 views.
So, even if I count only those views, I have at least 2,078 + 7,400 + 16,400 = 25,878 views.
According to Flickr, my photostream's view count is 17,757, which is off by a third. Interesting. Also, this kind of analysis is the mark of obsession. :)
