So I've been using Google Reader for sometime but today when I logged on I got a message that it will be closing down. I love RSS since it brings me all the content I like without having to search it out. Then I did some reading and found out that many internet sites are phasing out RSS. This model of content delivery seems too good to just die. Is anything in the works to supersede RSS as a content delivery mechanism?
Atom was specified as an RFC in late 2005, compared to the current version of RSS, 2.0, in September 2002, and specifically as a replacement for RSS. That would seem to qualify it to "supersede RSS as a content delivery mechanism".
The linked article specifically states that "These days people tend to use Facebook and Twitter as de facto RSS readers to monitor their favourite sites and subjects. Content providers also favour these channels as they make it easier for them to analyse and monitise their audience.". So there's your answer to "what else to use?": Facebook and Twitter.
Note that at this time, at least as I understand it (I don't even have a Google account, personally), it's only Google's RSS reader that is being discontinued. Of course, since it is web-based, you can't simply keep running the last released version locally indefinitely.
When the customized google home page was discontinued (which I was using to read rss feeds), I switched to Netvibes. It has some very nice options to follow RSS feeds.
Take a look at Rosselo, the brand new web-based dashboard application with different attitude to newsfeeds, giving you the better oversight of your news.
