I shed a little tear every time I receive a reminder email from Google telling me about the looming closure of the Google Wave service. I really liked Wave and where possible I tried to use of it when discussing or reviewing concepts with project team members. I’ll miss it when the service is turned off on April 30. Here’s a composite of some screen captures from one of my Waves. I also exported this Wave as a PDF with attachments (PDF, 544 KB).
