I found the prototype page of the upcoming PLoS One. It goes by the subtitle of Open Access 2.0 and according to the webpage it will try to change a lot of things about science communication.
Later this year, PLoS will launch PLoS ONE.
* A peer-reviewed publication that publishes all rigorously performed science
* A vibrant online forum that encourages scientific dialogue and debate
* A "hassle-free" process that gets your work online within weeks
The details are not obvious from the webpage but it looks like there will be a fast formal peer review followed by a community discussion. There will be a continuous revision process (interactive papers) and some tools to personalize your content, to find the stuff that interests you within the things published in One. The name itself is promising since it almost states that One will be the new flagship for PLoS.
There is also a link to a PLoS blog but it looks like it is not available yet. I am happy to see PLoS picking up the science 2.0 meme and putting some of it's weight behind it.
