After a hiatus of a few months I've again begun using Safari with "Blogger in draft " (I don't recommend trying Safari with regular blogger). I figured since Chrome uses WebKit that Google might have fixed some Blogger problems.
It's much improved, though there are obvious quirks especially with "BlogThis!". The pseudo-HTML view is now clean, without the carriage return/span/paragraph tag mess of months past. I love the ability to resize the editing panel beyond Google's mail slot standard. This is a feature available only to Safari (and Chrome?).
It's probably worth a cautious look. I'll report back here if/when I run into problems.
Update 1/7/09: Nope, not quite. Too many odd problems. For example, when I quote a series of paragraphs extra line spaces are introduced that I have to manually remove. Not to mention that the creaky old BlogThis! blogger bookmarklet works quite poorly with Safari.
It's back to Camino/Firefox again.
