Explore is great if you want to view:
Sunsets
HDR Kittens
Flower Macro
Birds sometimes
HDR anything really
More Sunsets
edit re. pete Semi Nude ladies, im pretty sure its the artistic content of these images that produces all the hits
and other such stuff that clutters flickr
Infact one of the most popular pictures i have seen of late was a combination of HDR a kitten a sunset and an iphone created as a joke it got about 300 comments and now flickr are using for promotions!
It is in no way a measure of how good your photos are, i know plenty of people that change their dates of their photos if they get on to Explore cos there comments are clogged with horrendous Gifs and 'Post 1 comment 245 thz iz tha bst pic evazz!!'. Though some people love the exposure.
(not to say yours is bad its a good sharp pan)
