Twitter is a useful tool. Its handy. Simple to use. Less boring as I don't need to read zillions words to get the point.
Just type what you are doing in 140 characters or less and interested people will get it.
Developers started to build really nice websites and clients on top of twitter. I spent the last week playing with the twitter API and I have some good news for you.
I will create a new website, that allow you to login using your twitter account. You can then twit Google Earth locations and landmark. That's the only function on the site.
The site will contain Google Earth plug-in, a Box to type your status and one Update button.
The name of the site is earthtwit.
Lets hear your comments and suggestions.
EDIT: The site is up and running now
visit it here
