It’s obvious but the pictures in my Flickr stream that has the most hits are not those that I think are the best shots. Instead, it’s those who are linked to high profile sites for illustrations.
For example, I had this picture of book and hands taken few years ago in a book swapping event. It’s linked in several sites, including high profile one like Ars Technica. Probably that also boosted the Google ranking and other sites can find it more easily.
The largest chunk of hits still came from Flickr search and streams as well as the privacy conscious “I’m not showing referrer” folks, but yeah, the hit count would jump up when the pictures are linked again in new articles.
I guess that speaks for our modern days of abundance (too bad gold and food is not in abundance). There’s just too much of something, we need a short list to keep it within the small limit we are able to bite off.
Well, first phase after uploading would be putting extensive and related tags. Seems like search engines also look for those.
