Ijustwenttothebathroom.com is a new Google map mashup about to launch with backing from the likes of Sequoia capital. The new mapping Web 2.0 site invites users to log in and post when they went, where they went and how it all came out.

“I think we can collect some valuable data that’s just wasted now,” said the site’s CEO.

Users in the secret alpha have already identified such trends as the Kansas afternoon flush, and the New Jersey midnight dump. Beta launch users will be by invite only, building up to the official launch sometime after the first of the year, 2008.

Real time maps will be available to all visitors from launch and are mapped by zip code and color coded on a yellow-brown gradient.
