What is your opinion about the
My Guests feature?
Personally I don't find any use for it. First, most of my entries are locked but even if I hadn't locked them I wouldn't use it. I think it is a good admin tool for the LJ staff to take care of stalkers and/or trolls, but regular users won't get much of it unless they will rely on this tool to remove those who don't visit their journals and friend those "random viewers" that have common interests with them.
I turned it off, it makes me uncomfortable to keep tabs on those whom I choose to know me.
