All the excitement in the internet world now (sometimes termed as Web 2.0) according to me can be summarised in 4 Cs:
* Content (Micro chunking. tagging)
* Connectivity (Communication, Mobility, RSS, Voip)
* Community (Collaboration, smart mobs, user generated content)
* Commerce (platform providers, Craigslist)
Internet is a Car. Content the driver. Connectivity which is the engine. Community the passengers. And Finally Commerce the spark! After you start the car – you actually may not need the spark.
