This is merely an idea waiting to be clarified but I just logged in and saw this after a few days off-Jive,
When the stream was called Comms it was understandable, after clarification from Josh, that it showed you stuff you had created.
But now it's called Inbox I'm less sure that seeing stuff you have created like Status Updates is intuitive or that I could justify it to a new user. For example, why should you need to read a Status Update you created. Wonder if there needs to be an 'All' filter and that the default now needs to be just the inbound stuff you are following or stuff you created where there has been response(s)?
