Is there any way to send a private message to one of your contacts? I saw, that we can share something with a single person and this "message" will either show up in the recipients stream (if he/she has added me to one of his/her circles) or in incoming, visible just for him/her and me.
Problem is - if my note goes to the stream and the others stream is update quite frequently (too-many-people-in-circles), then this private message will just get out of sight...
Anything I haven't discovered yet? Any rumors that private messages will be added to google+ during beta?
