More Google Apps coming
We set up all of our clients on Google Apps for email, wikis (google sites), calendar, etc. We use the same applications internally, and quite heavily. Google has just announced that this fall, there will be many more applications available in the Apps Suite, including Picasa, Reader, AdWords, and much more. Please see the official announcement for more details. We've signed up to be beta testers, no word yet on if we'll be in the beta program or not. We'll keep you posted.
