Postr is an app for the Gnome desktop, developed by Intel engineer Ross Burton. It worked fine for me until recently – first Flickr changed their accounts from Yahoo to own ones, then they swapped all of their our content from the Yahoo servers to the Amazon AWS cloud of their new owners, Smugmug. All of that went fine, but as a result, Postr doesn’t work anymore with their new OAuth login method, as this issue acknowledges.
Too bad, it’s a nice little program…
