When Google introduced GMail and a friend was kind enough to invite me to become a GMail member, I thought, this could be the best web mail ever. I had been using Hotmail and Microsoft whatchamacallit before then and they were pale by comparison. Not to mention the ever so clunky Outlook Web Access my previous company had which I totally refused to use. I joked to a friend that if GMail would have a calendar utility in it would be the Killer App on the Internet. She corrected me by saying that Yahoo Mail already had a calendar utility (plus a lot of other things). I could not really explain why I did not switch from the rudimentary GMail to full-feature Yahoo Mail then.
But now Google has introduced Google Calendar. I believe Google attempt at World Domination is complete! Well, almost. If it starts to have integrated and seamless wiki and blogs, I don't think anybody would need to use anything else. Will I still be using WordPress when that happens?
