Having RSS feed authentication method so that whenever there is an update, you can receive it on any devices using a RSS feed reader, would be quite nifty. I don't personally know how it works, but I know its been done. RSS feeds that are secured, and you can use your feed softwares (I have a Chrome App and Phone App for RSS feeds) that would show a popup whenever something happens, thus disabling the need for emails (in my case) ... When I check my feeds is usually when I have time to do stuff. Its how I receive my Manga and web comic updates, so when I am in there, means I pretty much have time to spend.
I don't know if anyone else would agree with me on tha tthough, RSS-feeds are becoming quite outdated... but still so very useful.
