Tools to create innovative applications and services are available and easy to access, usually they are free.
- The computing power of the cloud (Google App Engine , Amazon Elastic Compute Cloud EC2 and Simple Storage Service S3)
- Creation of location/context aware applications that use maps (Google maps) and GPS or cell-ids information (iPhone, Android, Symbian)
- Creation of social applications with the ability to connect with other social networks in the net (Google Friend Connect, Google OpenSocial, Twitter API, Facebook Connect)
Since the barrier to entry (and exit) is quite low, the competition abound, but if it is fun it is worth trying.
