That's about to be me, I think. Voluntary incarceration, perhaps, but incarceration nonetheless.
It started slowly - I got a G-mail account a few years ago. Never used it much, mind you, but I had it. And therefore, I had a Google account.
I've been using Blogger for several years; that was fine, but now Google owns Blogger, and I sign into my Blogger account with my Google account. Picasa? Same thing. Soon, You Tube will also be connected to my Google account, since they're now owned by Google...
I've also contributed to this domination - I've started using Gmail a lot more now, too, ever since I learned that I can check my other email accounts via Gmail, and I can send from them, too. So, I can check my email anywhere...
I've also set my own customized iGoogle as my Home page when I open my browser. iGoogle has let me customize the page in a way that suits me - it loads news headlines from sources of my choice, shows my email inbox and a calendar. I've even got my Google Bookmarks sitting in a widget on the page.
It's a bit frightening to think about how much information Google now has, but as their slogan is "Don't do Evil", perhaps I can trust them...
