Dear Tumblr -
I spend a great deal of time looking at my Tumblr stream, and I often discover — without any automated help by Tumblr, mind — that two or three of the folks I follow have posted something about the same news story. It would be great if Tumblr could provide a view that would consolidate these posts, and then allow me a way to create a post that referenced a/ the original story, and b/ include links to the posts of those that I follow.
Maybe you could pin them together at the top of my dashboard with a big red pin? Oh, wait, you are renting that space now, instead. What was I thinking. However, I would be willing to pay like $3.50/month to have the sponsored posts turned into this ‘confluence’ feature, instead.
If you don’t want to code this from scratch go take a look at Zemanta, which has a so-so user experience but has the plumbing necessary. And, oh, if you buy Zemanta and bake it into Tumblr, that would be a good smack in the face to Wordpress, too.
