I've probably had around 10 photos Explored since the back end of 2012, and I've uploaded almost 9,200 now. Do the maths - as a percentage, that's absolutely dreadful. I don't particularly care at the same time - I'd prefer to know that people who like buses are viewing my photos rather than complete randomers with no interest for buses at all. This photo got in excess of 26,000 views and 30 favourites - but as it wasn't Explored, it seems better in my eyes as it came from people in the hobby. Similar story with my most faved photo.
As everyone else has said, Jimmi, it's nothing to worry about. Take it in your stride - if one of your photos gets Explored, congratulations, you've done something (whatever Flickr thinks that is) right. If not, it's not the end of the world.
EDIT: The amount of views a photo being 'Explored' is much more significant than it was a few years ago, but that's because Flickr now counts a view if a photo appears on a page, and you don't have to physically click it to get a view. The photograph below was 'Explored' - which says it all:

Two other photographs I uploaded in December 2012 were also explored, bizarrely, and none of them were particularly great photographs.
