Grease your Chrome
OK… get your minds out of the gutter.  After a couple of years of being in total love with the combination of Firefox Greasemonkey, I started using Google’s Chrome browser.  Right off, I missed the functionality that was gained with the Greasemonkey plugin and various scripts that I had downloaded from userscripts.org.  After a few weeks of using Chrome and realizing that its speed has won me over, I thought I would look around to see about using Greasemonkey with Chrome.  I found what I was looking for tonight in Greasemetal.
Greasemetal is a userscript runtime which hosts javascript files for use with Google Chrome just as Greasemonkey does for Firefox.  I have tried a few of my favorite scripts for Flickr and all seem to work well so far.  Check out the Greasemetal web site to get the installation file.
