From time to time I try other RSS/ATOM readers, but (so far) I have always returned to Feedreader. It is free, simple to use, has a small memory footprint and good performance.
I particularly like its Intelliupdate feature that automatically adjusts when a feed is updated on the basis of how often it has new items, rather then the usual “update everything every hour” or whatever period you choose. Feeds can of course be set to update at specific intervals, from one minute to seven days or manually, if desired.
Version 3.13 has just been released and along with the usual fixes adds search engine feeds and multiple archives. There is also an experimental feature that allows the adding and editing of articles from Feedreader and other sources, the aim being to evolve a personal “knowledge base” facility.
One feature that I would really like to see is the ability to show a feed as an image gallery, much as competitor Blogbridge can do. I have recently subscribed to a number of Flickr feeds and this ability would be a very useful addition to the program.
If you are already a Feedreader user, then the new version is definitely worth installing; if not, and you’re looking for a no-nonsense RSS/ATOM reader, a test drive is recommended.
