For example, say I was typing this entry as public but wanted to add comments in that would be private, I could add tags such as:
<lj security="Private">blah blah blah</lj>
Or something as such, I've not really thought about the syntax but this would enable users to be able to 'annotate' their public posts with Friends-Only or Private notes... I guess it's just me being lazy but it saves adding another entry to my journal to make these thoughts... Not sure if this has been suggested before... Thoughts?
