When the app works its great. But that seems to be rare these days. The services that drive this app dont respond or timeout in a timely manner. So that results in the app looking like it is trying to do something only to leave you disappointed after waiting.
Flickr was the one Yahoo service I thought might still get some attention as they are in the their death spiral. It would probably be better for them to sell this service to some other company thats willing to invest in it and make it work.
