Why can't we have both? Sometimes I just want to bookmark a textual article, and Pinterest doesn't let me because it doesn't have an image. I have to manually search for any image on Google Image search, save it to my desktop, upload that as my Pin and edit the url to point to the text-only article I wanted to bookmark. Other times I want to bookmark something with a thumbnail, so Pinterest or this Kippt would be great, while Chrome's bookmarks, pinboard.in, a text file, would not be great. I want something that supports both, so I could save all my bookmarks in one place and be able to search for "something from 2-3 days ago" regardless whether it had a picture associated with it or not. Personally, the most important feature of a bookmarking approach for me right now is the ability to see a timeline of things, most recently added first. Filter by tags, search, etc. second.
