Flickr tempting me to upgrade…: Ok Yahoo, you guys are finally tempting me to upgrade with the 3 free months offer. But why should I pay to let other fine folks get to see *my* photos? I don’t use you for backup, I have network servers for that. I use you guys to show off little bits of my life as I tour the world. Maybe I need a tip jar to accept donations from my viewers who like what is posted… Ideas?
