Tuần này, Zimbra đã được Yahoo mua lại với giá $350M . Tuy nhiên, cũng như Yahoo Mail beta, nó vẫn quá rờm rà, đặc biệt là có vấn đề khi dùng trên IE vì có quá nhiều Javascript. Tôi vẫn thích Gmail hơn bởi vì họ có phần nhận diện tốc độ truy cập, nếu mạng quá chậm, giao diện sẽ giảm đến mức tối đa, còn Yahoo thì phải chờ mệt nghỉ!

Earlier this week we wrote about the classic approach to the semantic web and the difficulties with that approach. While the original vision of the layer on top of the current web, which annotates information in a way that is “understandable” by computers, is compelling; there are technical, scientific and business issues that have been difficult to address.

One of the technical difficulties that we outlined was the bottom-up nature of the classic semantic web approach. Specifically, each web site needs to annotate information in RDF, OWL, etc. in order for computers to be able to “understand” it.

As things stand today, there is little reason for web site owners to do that. The tools that would leverage the annotated information do not exist and there has not been any clearly articulated business and consumer value. Which means that there is no incentive for the sites to invest money into being compatible with the semantic web of the future.
