Flickr has an algorithm that it uses to determine the "interestingness" of a photograph. It's a combination of how many views the photo has received, how many people "liked" it, how many people engaged with it with comments, and how fast all of this happened. It's a fairly accurate gauge of how well received, and generally how interesting your photo is. Notice, it doesn't gauge how "good" a photo is; that's too subjective for any algorithm to figure out.
I've uploaded 679 photos into Flickr in the last 6 months or so, and the following 5 are what my audience find the most interesting. The first was shot with a Canon 5D MarkII 50mm, and the next 4 were taken with an Olympus E-PM1 45mm.
