Contemporary trends of internet services

Internet has been a common part of our private and work-related lives for a rather long time, yet it doesn't seem this is going to change. On the contrary - the importance of Internet is steadily growing as well as number of it's users and only few technologies have similar impact on individuals or even whole businesses and industries. But Internet evolves as well and it is not the same that it was 10 years ago. Today, Internet is more than just email or static (business) presentation on the web; it's more an interactive medium and is often associated with so called "Web 2.0". Yet even this concept isn't likely to last forever. That's why I find important to focus on contemporary Internet trends and try to describe some of the most influential ones regarding the future, i.e. social networking, wiki systems and blogs, APIs and mashups, but also Creative Commons licences and possible solution to multiple online identity issue, the OpenID project. Although I'm going to use particular examples of services in order to describe some of the trends, I would like to avoid unnecessary details. I'm going to focus on features the services have in common, not just considering particular service categories, but across the Internet as a whole as well. The aim is to create a survey, evaluation of contemporary Internet services and describe some approaches to solving specific issues related to this environment. Information resources will be mostly technologically oriented servers, blogs and other contemporary trends or particular product related websites. Obviously I'm going to embed my personal experience as well
