Rant: Would it be nice?

I'm subscribed to many social media bookmarking: Del.ico.us, Google notebook, Google readers, and plus my browser, firefox's bookmarking function. Each one of these services has it's advantages, and I have a humongous amount of bookmarks on each. Here comes the frustration then. My collection of bookmarking, clipboard of web content are segregated on each. Syncing them is tidies and a nuance to do, in addition that not all content can transfer.

Wouldn't it be nice if there's a service where I could access and search my collection as a whole? With standard categorization, tags... If I search for design inspirations, the things I bookmarked on Google Readers, the bookmarks I added in Del.ico.us & Firefox, and clips of the web pasted in Google Notebook would all show up. Would that be nice, ah?
