More media, more interactive, more collaborative, more stigmergic.
I was able to draw, create stickies-like notes, connect them mindmappishly, do an image search either online or on my computer within the workspace window and just drag and drop it in. And of course the best thing (although i haven’t tested it yet so I can’t vouch for its capacities) is that the workspaces are synchronous collaboration environments supporting chat and even voice chat.
I’d really like to see support for embedding sound, video, and well, why stop there, let’s have video chat as well!
ConceptShare.com looks nifty too but I haven’t had a chance to play with it yet…
