That’s the big secret, by the way.  For months I couldn’t work out exactly what Google Wave was, but now that I have it, I see it’s just a collaboration tool.  A really cool one that works over the ‘net, but in the end, it’s just that—a tool for folks to work together in real time over the Internets.  Don’t know why they couldn’t just bill it that way instead of explaining it in the form of a really much-too-long video.  It’s Google, it’s not like they won’t have people pounding on their door to try it out anyway.  So, why create the buzz?  Ah well…
