Google just announced Apps Marketplace, igniting a torrent of applications that all work online. If you have one of Google's free-for-the-taking hosted-domain apps accounts, once you log in, you'll be able to access all of these additional tools. There are 50 of them so far — mostly for business use — and that number is certain to grow in number and scope. With your permission, the third-party applications can access any of the data in your Google Calendar, Gmail, documents, or contacts. See the video below for a more detailed explanation.
But what about privacy issues, and the concern many businesses might have when their valuable data resides in the hands of someone else? Since we're the business of encouraging people read our stuff online, understandably, many of us aren't too concerned about keeping much of our data on a third-party server up in the cloud.
How about you? If Google soon offers every imaginable application (some free, and some paid) and keeps your data on its servers in the cloud, are you too paranoid to take advantage of it?
