Personally I will be upset to see this. Much of my traffic here on Blogger comes from those RSS feeds through my hubs.
Since I don't get much traffic flow from HubPages where I have not included RSS feeds then I can see a future drop off in traffic to my blogs.
I guess it had to come. We all have to move with the times and things do change. It will be sad to see the RSS feed go though, they did carry information for several posts and it meant the spread of other blogs and past posts was available to a wider audience.
Anyway there are about eight weeks to prepare and I am looking at possible reductions of my blogging and focusing on other things in the coming year anyway.
