The other tip I've been wanting to share is about dealing with multiple accounts. For example, for this new version of my Blogger book, I've created an example blog written by the fictional Sarah Cookwood. She has her own Google/Blogger account. But if I'm blogging from her point of view and blogging my own blog at the same time, I end up doing a lot of logging in and out.
Another situation where this might be an issue is if you share a computer with a partner or sibling. You log into your Gmail account and check your mail. Fine. But then the other person comes along and wants to log in. Again, there's a lot of logging in and out.
My solution is to use two different browsers... for example, Sarah can log in with Firefox and I can log into Safari. We can both stay logged in and let the browsers keep our accounts separate. If you're on Windows, one of you could use Firefox and the other Opera, (OK, or Internet Explorer).
You could do the same thing with Facebook, Twitter, or any other site that you need to log into with more than one account.
