Because adding a counter used to be customization territory, I think that adding 3 sentences or so to this FAQ linking to the Howto post on adding a counter would be a helpful. I link to this FAQ in every answer on counters I give, because the only way to know exactly who has access is to go Friends Only/Private.

While you can restrict who is allowed to read your journal, it is not possible to know exactly who is visiting your journal. You can, however, add a hit counter provided by a third party. To find a source for the counter, you will need to locate one that does not include the use of a scripting language (for more on this, please view http://www.livejournal.com/support/faqbrowse.bml?faqid=14 ). This post: http://www.livejournal.com/talkread.bml?journal=howto&itemid=1332 from the Howto Journal ( http://www.livejournal.com/users/howto ) explains how to apply a counter to your journal.
