I was excited to notice that clicking "compose" in Safari (actually, a recent Webkit nightly build) doesn't give the "It's not going to work, even if we love you" warning anymore, but after trying it -- it should be there!
For starters, in Safari some of the formatting buttons aren't there (who cares) and more importantly the _link_ button isn't there (argh!).
Here's Firefox:
And here's Safari:
Ooops! Makes it hard to make link-y vox-posts!
Second problem I noticed: When I uploaded the pictures with Safari they ended up looking funny (they showed up next to each other). I tried clicking between them so I could add a few lines between them - which took me to my Vox page. Oops. Clicking the back button took me back to a blank Compose window that now wasn't editable!
So, dear Vox-creating-friends: Please either add the "It's really not going to work, just give up now" warning back, make it work in Safari or ... I forgot option 3, but option 3 would work too as long as it involves your awesome problem solving skills.
I try to use Firefox, but it just doesn't feel slick and pretty enough. Safari/WebKit is slick and pretty. Oh, and feels faster. I know it's supposed to be the other way around.
