Can you remember when it was a big deal to have your own Gmail account? It seems a long time ago now, but Google Wave could attract similar attention, with its combination of functionalities and real-time interaction features. Google will be inviting over 100,000 to test Wave today, though unless you were very early to the punch or have been involved in the developer preview then that is unlikely to be you. If you do not know much about Google Wave, then you can take a look at the 80 minute long video of the preview presented at Google I/O 2009. If that is a bit too much for you then fortunately there is a much shorter video that highlights the important principles.
Of course, as with anything Google launches, there has been plenty of interest in Wave, with some seeing it as having the potential to evolve the way web users collaborate. Others are more sceptical and do not really see it offering much that other web services already provide. Engadget went hands-on with the developer preview back at the start of last month, which shows some of the ideas at work. Is any of that enough to get you excited about trying it out?
