It's been two years since CSU Monterey Bay took Google Apps to be its lawfully wedded cyber-spouse. (Aren't June weddings wonderful?)
CSUMB kept one relative in the attic for about a year: FirstClass was our departing e-mail client/server system and we kept it in the background to be able to access our old messages. (MeetingMaker, the campus's official scheduling software, simply disappeared like an angry ex not invited to the nuptials.) Meanwhile, Google brought a passel of its own kids into the relationship. But only three were invited right into the house and given their own bedrooms: Gmail, Google Calendar, and Google Docs.
Other Apps such as Sites were left to fend for themselves at first. Instead of prominent CSUMB dashboard links, for example, there would be smaller links on our Gmail page, that sort of thing. Over these two years, most of my students had never even clicked on the Sites link until required to do so for my class. (That's not a complaint, just an observation that you get the behavior you design for.)
Google Docs may finally be in early majority stage, beyond the early adopters. After a year or so of "But we need Microsoft for everything" and about 50 other excuses, I'm seeing it used more for collaboration by known non-techie faculty members.
Here's an interesting commentary on how the first two years went (but nothing about a 2nd Anniversary Celebraganza??) by Greg Pool, who is CSUMB's Lead Web Publishing Coordinator. Greg has some intriguing comments about Google Moderator. I thought I would be one of the first to use it on campus next fall, but apparently somebody snuck by me!
