I've also set up a new category, so you can always find all the articles on Sony. Our topics are now:

SCO
Microsoft
Patents
News Stories
Daemon
AntiFUD
INFO
Standards
Sony

These are now the categories of stories Groklaw regularly covers. For Groklaw members, that means you can go to your account preferences and choose to exclude any category you don't want to read, and obviously that means by narrowing it down to one category, you can find all stories on a particular topic. Of course, that depends on me to remember to always set the topic for each article, and you know me by now. On a crazy news day like today, sometimes I forget. But I try. For the public, the permanent Sony page provides another option.
