One of the drawbacks of blogging as a platform is its dependency on chronology. When a reader comes across a new blog and decides to begin following it, he or she typically reads only new posts from that point on. Some may peruse the past few months worth of posts out of curiosity, but few if any will start from the beginning (unless, of course, the blog is still fairly young).
This isn't a problem for the author as much as it is a lost opportunity for the reader: If you just found this blog today and decided to add it to your RSS aggregator and simply follow new posts, you've missed out on three years' worth of information. Granted, maybe only a small portion of it is of interest to you, but that's still a good deal of potentially beneficial reading.
This has bugged me for some time but it wasn't until today that I set about implementing a solution. I've created a secondary RSS feed which essentially republishes blog articles on their three-year anniversary. As an example, if you were to view the feed on June 1, 2011, you would see articles published June 1, 2008 or earlier. (Blog articles from the delayed feed are tagged as such to avoid confusion.) The idea is that newcomers can subscribe to both the normal live feed to follow new articles and the three-years-delayed feed to gain exposure to older articles they've missed. This allows the reader to digest older posts at a casual pace.
One issue with this, as you might have guessed, is the handling of outdated articles. For example, you're probably not interested in reading about three-year-old IOS vulnerabilities (though to be fair, this would be of benefit to more than a few organizations). To avoid this, I've excluded posts categorized as news, announcements, rants, or opinion. This, presumably, leaves only objective technical content with a much longer shelf life.
The delayed RSS feed is available here. At the time of writing, the feed is still blank: The first article, published March 28, 2008, should appear Monday. I'm writing about it today to see what people think. Is it a decent idea? Not so much? How would you tweak it? Let me know!
