The simplest way to bring back RSS to Safari is with Daniel Jalkut's extension.
Mountain Lion’s version of the Safari browser brough many great things: a unified URL/search bar, iCloud tab syncing and some neat new gestures (try pinching when you have a few tabs open). What it also did was remove the RSS button, replacing it with the Reader button found in iOS. This – apparently – pissed off a lot of people.
So, for those of you who used this button daily, we’ve put together a list of alternatives. None of them will give you the same functionality, but all of them are great RSS readers which work in slightly different ways.
Readlinesmakes great use of your iOS device while it’s sat in its dock on your desk, and turns an otherwise boring blank screen in to a big, bold stream of random headlines from your Google Reader RSS feeds. In the same way that the recent Trickleapplication displays tweets from your Twitter feed, Readlines cycles through your unread stories and displays a constant stream of headlines. Clicking on a headline that interests you will take you straight to Safari where you can read the whole article.
If you use your Google Reader account like I do, you’ll get hundreds of news stories every day that you’ll have to sift through to get to the good stuff that you want to know about. With Readlines you can simply get on with your work while your headlines are streamed to your desk, and it makes picking out only those that interest you incredibly simple.
