Edit: Added a cut and de-italicized. I guess that's what previewing is for. Heh.
Is there a way to track who reads my journal?
LiveJournal does not currently offer any means for tracking visitors to your journal; if this feature is offered in the future, it will most likely be available only to paid users.
Once you have created a counter on another site and have been given the HTML needed to add the counter to your journal or user info, you'll then need to decide where you want to place your counter.
To add a counter to your user info, simply cut and paste the HTML generated when you created your counter into the "About You" section on your Edit Info page here (http://www.livejournal.com/editinfo.bml).
To add a counter to your journal, visit the HowTo journal (http://www.livejournal.com/userinfo.bml?user=howto), which contains numerous tutorials that are indexed in the memories (http://www.livejournal.com/tools/memories.bml?user=howto). The tutorial that explains how to add a counter to your journal is available here (http://www.livejournal.com/users/howto/1332.html).
Instead of using a counter, you can choose to enable comment IP logging, which is explained in the FAQ here (http://www.livejournal.com/support/faqbrowse.bml?faqid=66). That FAQ also describes how you can use a visitor's IP address to identify his or her Internet service provider.
Finally, if you are concerned about controlling who reads your journal, you may want to change your journal's security settings, as explained here (http://www.livejournal.com/support/faqbrowse.bml?faqid=24).
