I recently started dabbling with building iGoogle "gadgets". If you aren't familiar with iGoogle, it's a service from Google that allows users to create a highly personalized web-based portal with various pieces of news, weather, content, and a slew of other types of web-based applications in one handy location. It's the first place I go each morning to view my local news, check the weather, monitor stock prices or even kill time playing silly online games during the long train ride to work.
If you're a serious application developer, iGoogle provides a robust platform on which you can build some pretty sophisticated web-based applications. With an estimated user-base of 25 million users, it's also represents an intriguing business opportunity.
