It (temporarily) replaces all the guts of Safari, everything but the outer interface. WebKit is the underlying web engine used by Safari, Help, Mail, a few other parts of OS X.
Your original Safari remains intact even if you run this, the kit is arranged so that it doesn't change the installed version of the libraries.
It "does" all kinds of stuff, being a newer version of the library that ships with Tiger. It gives you many of the changes that will be seen in Leopard. There are a few speed tweaks, better compatibility with sites here and there (and worse on the parts where they're still working on it), a neat litle web inspector panel that lets you examine the structure of a site, plus a bunch of other little tweaks here and there.Oh ok. But what does it do? Does it increase speed?
There are a few speed tweaks
How does that make it not true that there are a few speed tweaks? The illiteracy on MR never ceases to amaze me.That's not true, the build I just downloaded is much faster the Safari 2.0.4

And I have to download it every night?
Does the WebKit leak memory like Safari?
Can this be run on the earlier versions of safari? In OS 10.3.9 the latest safari allowed is 1.3.2. Can I safely run the webkit?
