If you go to the homepage, you'll find another new brick there, called "A v. B".
It shows two photos from our database side by side. There are two buttons above the photos, labelled "photo A" and "photo B". Click the button above the photo you prefer. You get two new photos. Lather, rinse, repeat.
We'll add this to the photo index page shortly, too.
Who can vote?Anyone, member or not, can vote using this feature. We're hoping that this will encourage them to keep on clicking, see lots of great shots, and want to sign up. It also makes the stats more meaningful, as we'll have more votes.
Can I vote for my own shots?You shouldn't see your own shots in there while you're logged in.There's nothing stopping you logging out, of course, but you'll still have to keep hammering at it till one of yours comes up. You could be at it for a while...
There are some protections in place against gaming this, too. And they work. I've tried them
What happens to my vote?At the moment, we don't do anything with the data. Later, we'll add something like an "A v. B Top 100". We may also figure out ways of promoting the shots that consistently come out ahead (but I admit that not much thought has gone into that yet!).
What we won't be doing is a full list in order of popularity, a "loser list" of shots at the bottom, or anything of the kind. This is meant as a way to figure out what people like and bring that to the fore... not to show what people don't like.
How does it choose the photos?It's completely random (although sometimes a clever juxtaposition of two photos makes it look much smarter than that!). It uses all photos, regardless of whether they passed quality screening.
Anyway, we hope you have fun with this. During final testing, I found myself thoroughly engrossed, discovering some fantastic shots I never knew we had... I thought I'd seen them all, but I wasn't even close!
