"I heart Pittsburgh" is acceptable as it's more of a "look". It's like an "I heart NY" t-shirt. But koalas and horrible lurid 80s Ken Done stuff - revolting.

To be fair to these sites though, they are not easy. A former friend of mine (no falling out, just drifted apart [he went to Brazil :D ] ) is a bit of a photog. I'm not. He told me that one bright, cloudless day, as an experiment, he went down to Circular Quay and tried to take some "postcard" shots of the view. Nothing arty, just clear, full colour panoramas of the SHB, Opera House, and harbour. He said it was the hardest thing he'd ever done, and he simply could not do it. Every photo had an obvious flaw.
