All the major news sites, blogs and forums display links to RSS feeds (ie.:Apple RSS). You can subscribe to the feeds in two way:
- Copy the link from your browser and then add it to Newsflow with File / Add subscription
- Click on the link. In Safari you need to click cancel for the window asking you to add link to shared link.
As Newsflow does not have a built in feed recommender system we suggest you to check out Feedly. It is a free service and has great recommendation system on their website. After subscribing to interesting feeds you can easily add your Feedly account to Newsflow.
