To at least give me some sanity while I worked I wrote this little Greasemonkey script that blocks Greader during my productive hours, 9-12 and 13-17. When I try to go to the site I get redirected to a site that reminds me what I’m working on, in this case the Java Language reference. You can easily add sites to black list through the Included Pages in the Greasemonkey management window. And the script is so simple that anyone can modify it to fit their needs.
