This post could easily have been named “Targeted Blogging” or “Feature requests for Feedburner” 
So I started thinking about a RSS/Atom feed that is intelligent. Meaning each of my blog’s feed subscribers can potentially be offered unique content. So let me present a few scenarios:
- Wouldn’t it be great to be able to write a blog entry about music, and have only people who had “music” as one of their interests, be the only ones who see it in their Google Reader/My Yahoo!/NetNewsWire ?
- What if I was organizing an event in San Francisco, and wanted to let only people who are in California know about it ?
Problems:
- Doing Geo Targeting for ads within feeds is easy, since they load within the browser as a separate request, hence the ad server can act with intelligence about time of day/location etc. Sadly the same is not true for my blog entries. I write them once.
- Scenario#2 above is a bit flawed, because what if my friend from NY is going to be in California during that time period, then he/she will not be able to attend, since my blog entry won’t show up in his/her feed!!
Solutions:
- When the user comes and clicks on my “Add to Yahoo/Google” button I ask them for some basic info, such as age/location/profession etc. They may chose to ignore it of course, but if they don’t they are giving me important information.
- A better solution is for feed burning platforms such as Feedburner to maintain a persistent profile of users who are subscribing to feeds. So my profile would read: “Sumit Chachra, Male, 26, San Francisco, CA ……..”. This information will *never* be shared with feed publishers, but they can use it to target content (much the same way Facebook ad targeting works)
- The problem with scenario#2 can be resolved using a few techniques. Assuming Google Calendar has a feature called “Location” where in I can feed in my coordinates for specific dates, and this information can be shared with Feedburner, then my feedburner profile is really “dynamic”! We’re headed down the path of intelligent agents here really, and its all starting to sound like a scifi (scary) movie at this point
All this implies that each subscriber to my feed has a unique feed url, which will spit unique content to each such subscriber, based on certain data points that the feed url platform knows about them, and using which the feed publisher can do targeted content delivery!
I wish this existed!
