I first used Fluid , the site-specific browser creation tool for Mac OS X, a long time ago. But I didn’t find it compelling enough to integrate it into my daily life, in part because virtually all of my digital life still lived on the desktop. As I personally moved more and more to the cloud, it became key. I tend to use Fluid apps for things that I want to have open and at the ready all day. These are things I consider to be more like apps than websites, so having a separate window makes sense, if for no other reason than I can easily command-tab among applications by selecting the appropriate high-resolution logo. With Safari , Chrome and Firefox , I’m in and out of a lot of websites throughout the work day, but most are content sites, or web applications that I use once per week or less. Here are a few of the key ways I’m using Fluid today. Google Calendar I long ago tired of problems with invitations in iCal. There were just too many frustrating examples of invitations not coming through properly or at all, and I invested the maximum amount of time I was willing to solve it. Last year, I also tired of Mail.app’s performance when dealing with many accounts and large numbers of messages. I was using Google Apps for several accounts with IMAP enabled, and using Mail.app as my client.
