I put my mouth on a low-hanging fruit by starting the /r/malespandex subreddit on Reddit. Like Flickr, delicious images are crowd-sourced, which means you get quality and quantity beyond what any one blogger can give you.
Maybe about a year ago, I thought to myself, I need to create some kind of gallery for my website where users would submit images or links to images, and they would be displayed depending on how many votes, how recently submitted, etc. And, of course, it’s a decent idea that was totally reinventing the wheel, so check if that wheel already exists and go use it.
I’m happy to say that /r/malespandex now has quite a few yummy pictures submitted by another kind user to get it started. You’ll see that I also have two posts there, and it should obvious what my Reddit username is.
