I wish I had a site like Notesake back then when I was at school and University, it would have saved me and my friends lots of time. Notesake is basically a group note taking online service where group of users can take and edit notes together. This is great for several reasons.
If you miss a class you still can take a look at the notes online without having to rely on friends who bring them to your house. Even better is that everyone in the group may edit or add content to those notes making it fairly easy to create a comprehensive summary of what happened during a course.
Once completed notes can be printed or exported in pdf and doc format for further editing or archiving those notes.
The editor can probably compared to Notepad with just a few needed formatting options added such as bold or underlined text and headlines. I was not able to find a way to upload images though which would be a real nice feature if you consider that many courses nowadays use graphics in their presentation.
Notesake converts mathematical equations into images and seems to support Latex although I was not really able to find any information on their site about the latter.
If they add private image hosting, offer a good online help explaining all the hidden functions and probably an import function they would really rock the note taking web. As of now this is an interesting online service that could to better.
