I have seen a lot of companies work in Web 1.0 yet and they are testing recently some Web 2.0 technologies (see Internet Banking, for instance), other companies have gotten great benefits by using Web 2.0 and SaaS (e-commerce, social content providers, etc.) Now, Web 3.0 or PaaS is a great breakthrough for companies by getting more elements to boost their platform and reduce costs.
