New start up Kiobo is entering the social recommendation space with its Firefox toolbar. Kiobo aims to make web browsing more social.
Users can see the real time surfing habits of their friends and the community as a whole. They can choose to focus in on one particular friend and see what he/she has recently browsed, what sites he frequents and what his tag cloud looks like—of course this is only possible if your pal allows it. Beyond that, Kiobo will take a look at your own browsing habits and make recommendations based on sites which your friends and members of the community who have similar interests like to browse. So, you’ll be able to meet other people with the same interests and browsing behavior, and become their followers. Kiobo displays popular sites in real time; and you can see exactly who’s browsing what. There are, of course, privacy controls put in place, so that you can choose to allow others to see what you browse or not.
