I hope you caught the announcement of Google Wave. Google Wave is "a personal communication and collaboration tool" announced by Google at the Google I/O conference, on 27 May 2009 and is expected to be released later in 2009.
This looks an amazing new collaboration tool (I'd even go so far as to call it a KM tool!) - see the complete guide from Mashable or the Google introductory video And aslo see the Wikipedia entry.
Google would like the Wave protocol to replace the 40 year old e-mail protocol and so are open sourcing the protocol and the source code. People have been predicting the death of email for some time and Google Wave might just precipitate that!
It's only too easy to get over excited by a new product but Google Wave looks like a major innovation and its development is worth following closely. Sign up here to be informed when it is ready.
And an interesting post from on Google Wave Implications On KM from Dinesh Tantri.
