Google Docs just got a lot cooler! Today, Google announced some big changes in the way Docs works. Most significantly, I think, the ability to see real time collaborative edits--no more having to save a file repeatedly in order to see changes. This is HUGE when several students are editing the same document simultaneously. Before, students could be editing the same sentence, without knowing. Now, changes appear in each document as they're made. Way to go, Google!
Docs also provides a collaborative drawing tool to create flow charts, diagrams, etc. which can then be imported into a document or presentation.
Not all accounts are updated yet (mine, for instance!), but Google tends to roll these things out in waves (pun intended...) If your account doesn't reflect the changes yet, sigh and be patient....
In the meantime, here's a video description of the changes.
