After I launched EarthTwit, the limitations started to appear. Downloading the plug-in for Google Earth costs. It costs time, it costs memory. Some people can't download it due to some permission on their machines.
Google Maps on the other hand work on most browsers without a plug-in. It loads faster too ( check this) . You will only miss the Earth spherical look on Google Earth.
So how about if we make people twit maps?
I love you all my dear readers. If you have suggestions don't hesitate :)
