It's a pity to see it go, also because I had some projects hosted there and moreover it was quite useful for developing and hosting iGoogle gadgets:
- News Mapper
Quite interesting product which got even mentioned on the official Google blog and appeared under the popular mashups of the unofficial Google Mashup gallery blog.
- Pharmacy Locator
Still not finished. The data has been added manually but I planned to retrieve it in an automated fashion from some source. I guess this could have become quite interesting.
