Apple’s Webkit is being built into all sort of Mac applications, however they all seem to share data and I don’t feel they should.

As an example, if you log into your Google account in Safari, Shiira is also logged in. And it doesn’t stop there. GCal, CSSEdit and Journler all use webkit too so you are automatically logged into your Google account.

This isn’t just a Google thing either. Works with Yahoo mail, Wordpress blogs and any site that has a checkbox for “remember me.”
