A small housekeeping change here at DF: each Linked List entry now has its own unique permalink URL. So, for example, yesterday’s link to Andy Baio’s interview with The Big Picture’s Alan Taylor has a permanent URL here:

The older month-based URLs still work and won’t change, but the new URLs are better, and, in hindsight, are the way things always should have been. You can also get listings by day and month by chopping the URL.
The only downside is that when the new URLs went live yesterday evening, the permalink URLs changed in the RSS feed. Depending on the behavior of your feed reader, this may have marked all previously read Linked List items as unread — an unfortunate, but one-time, inconvenience.
