So it turns out Tumblr search is broken as well. Any posts uploaded from mobile are no longer indexed as far as I can see and tags I follow have been removed if they are above N in the alphabet. This makes Tumblr next to useless for finding new content beyond the blogs you follow. This all happened when they changed the posting style on mobile. Not happy.
Also still not happy about the mess that is posting photo sets from mobile. These show up as low res text posts on web in some random order with the caption in the middle. Are we going to have to fix these posts once they fix their framework, or will they fix these posts they messed up?
