Web 2.0 has made life really for one and all. Never had the web been so useful for mankind like it is today. If earlier it was the commercial nature of web, it is the social nature that is making it popular and there’s no looking back.

RSS (Really Simple Syndication) will be the next iteration of commercial email.
Mainly employed by news sites and blogs to feed content updates to consumers who opt into receiving them, RSS, an XML format enabling Web syndication, is pull marketing at its best. For anyone with a message to communicate—from retailers to real estate brokers, it provides an instantaneous, automated, inexpensive way to message to consumers by providing the benefits of email— notice of sales, price changes, new arrivals, trends, and scarce inventory—without its drawbacks—irrelevant messages, inappropriate segmentation, spam, government regulation and consumer fatigue with unsolicited messages.

While RSS is a nascent technology, there is tremendous potential for its adoption because of its ease of use and flexibility. Several companies are enabling the growth of the technology — email service providers like Silverpop have already integrated RSS tools into its arsenal, and startups like RubiconSoft have enabled features for online retailers like Tower Records’ Tower Alerts, which notifies customers of new arrivals in music categories like jazz and classical.

Rich Internet applications will enable a great leap forward in usability
RIAs, primarily AJAX and Macromedia’s Flash and Flex, are already creating waves with many popular websites. AJAX is a Web development technique most popularized through Google maps—the ability to navigate around a map without refreshing the page. As the most effective usability experiences for any website involve the fewest clicks possible and minimal page refreshes, AJAX can simplify features like zoom, enlargements, graphics, tables and of course maps. While it may evoke groans from developers, it creates a more intuitive browsing experience for customers.
