Prosaic gold all the way down:
Flickr has taken some controversial twists and turns over the years (the last turn seems to have been into a ditch). They introduced a free, one terabyte tier a few years ago. It serves gross ads, and offers no first-party syncing, or downloading, off the service. The pro account now offers unlimited photo uploads at $24.95 a year. That’s a great value – if Yahoo hadn’t defecated on Flickr, set it on fire, and tried to put out the fire with urine-soaked novelty T-shirts that say, “We Hate You” in purple Optima.
