Getting through a long list of bookmarks to find that site you vaguely remember can be a pain. Zootool bookmarks with images, letting your visual memory help you locate sites faster.
After you sign up, Zootool provides a bookmarklet (but a third-party chrome extension is available as well). Like any good bookmarking web app, you click the bookmarklet to bookmark the site. Instead of a little info panel, however, Zootool runs through all the images on the page and gives you a nice little grid to choose from:
The Lifehacker main page
From there you can bookmark any image on the page, tag it and save it to your Zootool account. Zootool creates a feed of your bookmarked sites, making it like a hybrid between a bookmarking site and a microblog.
You can sort through your bookmarks really easily, since Zootool records what you've saved. Images, videos, pages and documents are all automatically categorised so you can switch between them and filter your content.
Socially, Zootool has a following system so others can see what you're bookmarking and you can follow people who are bookmarking items of interest you.
If a list of text links isn't cutting it for your bookmark needs, Zootool may be a good way of organising all those sites you want to remember.
