» What is "watching"? Can I view communities separately from the rest of my friends list?
"Watching" is defined as adding a community to your friends list. You can watch a community without being a member, or be a member of a community without watching it. Users who list the community as a friend are shown on the Community Info under "Watched By".
If you choose to add communities to your friends list but would like to view them separately from the rest of your friends, you have two options. You can use custom friends groups, which are described at http://www.livejournal.com/support/faqbrowse.bml?faqid=102, or you can append ?show=C or ?show=P to the end of your friends page URL (for example, http://www.livejournal.com/users/exampleusername/friends/?show=C) to only show entries in community journals or personal journals, respectively.
