Flickr in 2004 and have been posting photos there, on and off, ever since. For years, Flickr was the place to share photos and discuss photography. Then Yahoo neglected and thus helped ruin it. And of course Instagram eventually finished the job.
I dislike Instagram so much. Tiny, compressed photos. No good way to post from my computer. Terrible search. An unfathomable algorithm. Fucking hashtags everywhere.
And yet, Instagram is where everyone is.
