I keep trying to downvote things on Tumblr and Facebook ._. It’s so infuriating that I can’t do anything about the stupidity.
Reading tons of tumblr before bed = all dreams about cats, Asians, school, and hipsters.
1) Why doesn’t the dashboard show the dates of posts?
EDIT (4/1/2012): Yay they added this in the newest UI update! :)
2) Why is there a Preferences *and* a Settings? Does it have something to do with people that choose to have more than one blog, so each one could have different settings? If so, I still feel like there’s a better way to go about doing it and merge Preferences and Settings into one Settings page (maybe different tabs for each blog in the new Settings page?).
3) I don’t see the point in the separate personal tumblelog page (http://www.tumblr.com/tumblelog/username) and public page (http://username.tumblr.com/). I would prefer the public page to be replaced with the personal tumblelog page when I’m logged in and viewing it (so I still have access to all of the right-side links and the ability to make a new post within my tumblelog), with a button at the top to “View Profile As Visitor” to see how public viewers would see it (much like Facebook/Google+).
4) Compete with Pinterest, add categories and you’re golden.
Overall, navigation seems very unintuitive, clunky, and requires too much clicking around. KISS.
