This is a repost of a much older post that was lost when I transitioned from Moveable Type 3 to 4.
I personally like using WebKit nightlies as my main browser as it’s more or less Safari with a better, faster, and much more current rendering engine underneath it. That and the gold logo looks much better than the silver. It does have bugs occasionally (for example I was unable to post comments to Flickr with WebKit nightlies for a couple weeks) but all in all the experience is very positive. This is the script I use to keep WebKit updated whenever it bugs me for an update. I use an alias in my .bashrc file so I can just type ‘wkupdate’ to run the shell script. The best part is that if I copy it and I’m still using the program the changes won’t take effect until I restart but it allows me to copy it still. (Not advisable however)
