Social Networks and the Semantic Web
FOAFnet lead by Mark Canter is an industrial consortium of social networking services. They are adapting FOAF to be used as an interchange format between social networking sites (i.e. you can import your user profile from one system to another with the click of a button). SXIP Networks (pronounce: skip) start-up by Dick Hardt involved in the Digital Identity Management/Single-sign-on business, possibly adapting FOAF.

There are a plethora of bookmarking sites out there and only a few of them have become very successful - del.icio.us and Stumbleupon are two that spring to mind. Trailfire is a bit different from your average bookmarking site, because they don't just allow you to share bookmarks - they make it easy for you to share 'trails', which are "annotated navigation paths". Trailfire is a free service and is described as a way to let bloggers place multimedia rich comments on any Web page and automatically link related Web pages to form a trail, or navigation path. The product is a download plugin for Internet Explorer and Firefox. Interestingly, they claim it is "more complementary than competitive" with social bookmarking sites.Taxi in portugal are generally very cheap. This is why people, in particular tourists that come from richer countries, tend to take them a lot. But in Lisbon they are often not that honest. It is very common to take a taxi in Lisbon and end up paying much more than what you were supposed to. And what you are supposed to pay is what it is written on the taximeter (plus sometimes an extra of 1.60 euro if you have luggage), with the taxi having done the shortest or fatest route between the two points. It is not unfortunately uncommon to end up paying twice of three times what should be the real price by law.

Ontology is Overrated: Categories, Links, and Tags This piece is based on two talks I gave in the spring of 2005 -- one at the O'Reilly ETech conference in March, entitled "Ontology Is Overrated", and one at the IMCExpo in April entitled "Folksonomies & Tags: The rise of user-developed classification." The written version is a heavily edited concatenation of those two talks. Today I want to talk about categorization, and I want to convince you that a lot of what we think we know about categorization is wrong.
