Diigo, which stands for “Digest of Internet Information, Groups and Other stuff”, is a social bookmarking site that allows users to highlight multiple content areas, including pictures, tag the page, and bookmark it. Users can also add sticky notes to a highlighted text area. It has other good features as well – see the flash demo for a good overview.
Many of the bookmarking sites are starting to blur together for me. I like Diigo and the founders are politely efficient in getting the word out. The company has also executed well and released a polished product. But at the end of the day I’m not sure how many social bookmarking sites can make the cut.
I will say this, though. I like the idea of public and private “sticky” notes on a website (Activeweave promises this, and I saw a really great demo two months ago, but it hasn’t launched yet). And I also like the ability to highlight multiple areas of a website in my bookmarks (Kaboodle does a great job of this).
But, as you can see, for just about every feature, there are multiple companies already attacking the space with vigor. Good luck to all. It’s going to be a long, hard fight. With perhaps as much as a $30 million payout at the end of the day.
