Dave just added the notion of an idea stream. Basically as I understand it, this will work just as before, except that the RSS feed will no longer send out a separate post for each idea (I notice Dave has added a lightbulb icon which now characterizes each post node rather than the rectangles seen in the posts below). Instead the day/date will be what is sent out, and the posts – the ideas – will be listed as part of that post. So, this post will go out under a “March 17” post in the RSS feed.
This makes sense for a prolific blogger like Dave. It also makes sense for a worknotes outline – I have one of those but leave it private rather than a named outline.
