I think I’m slowly going to transition out of Flickr. 500px is a Toronto based startup that fairly recently, gained a ton of popularity. I just love how the photos are displayed (Pinterest-esque) as well as the ‘social’ aspect that Flickr was always missing. With Flickr, it always seemed like I was just cataloguing my photos rather than sharing them. I still have another year on my Flickr Pro account, but unless they change something during that time, I don’t think I’ll be looking back.
