An application of the Attention Economy

Seriosity is an interesting application of the so-called Attention Economy.

Good move, Second Life!!

According to Mark Wallace in this blog post, it seems that Second Life will open-source the server code. I think this is a great move from Linden Labs as it will attract many investments on the SL platform. Also, this way SL candidates itself (and credibly) as the next gen Web platform.

Ontologies for the Web's ??

Ontologies today lack of the flexibility needed for the Web. As a matter of fact, ontologies have been conceived for little communities of experts that try to agree on an "objective" model of a given domain of knowledge. To reach to an agreement about a model is often difficult, even in these little communities of experts. In large Web communities, don't even think about it...

So, should we renounce to ontologies as the foundation bricks of the Semantic Web vision?

I really don't know, but I'm trying to hint a possible solution of this problem.

Ontologies, as we intend them today, are based on Description Logics (DL). A Description Logic is based on an objective interpretation of the reality, not a subjective one. Nonetheless, there exist logics that model subjective interpretations (Epistemic Logic) and even subjective beliefs (Doxastic Logic). Is it possible that an ontology language based on the epistemic/doxastic logic would better fit the reality of the Web? Would reasoning be possible on models built with such a language?

Is there someone out there that can give me an answer?

Chip chip chip...

Twitter is growing fast. It is a sort of instant blogging for instant self-gratification: you just post answers to the question "What are you doing?", with a few words, as you were writing a SMS. This kind of service permits to a very long-tail of people with a little time or a little attention span or not being a proven blogger (like myself :-) to express themselves in the Net.

What else should we expect now? Maybe automatic systems, like meteorologic stations, could start twittering their data?

A Web of Metaverses or a Metaverse for the Web?

While Second Life is (inevitably) suffering of scalability problems, it becomes clear that a single metaverse environment is not the way to go. We rather need a "Web of Metaverses", all interconnected and where, possibly, there exists a notion of "Avatar continuity".

Good starting points to materialize this vision are:
