But I don’t understand what you mean by ad intervals in the daily posts.
The daily posts are the ones organized by day. There are two ways to get into them right now: 1) by clicking the ‘daily archives’ button that pops up a calendar to let you choose a day (e.g., that’s what I use when I want to know what I posted last Tuesday), or 2) clicking the link at the top and bottom of the front page center column, that says ‘Yesterday’.
