RSS Popper - RSS Reader for Outlook
RSS Popper is a simple barebones RSS reader for Outlook.
I use NewzCrawler as my main aggregator, but I subscribe to probably too much RSS feeds, so it's a distraction to have it opened the whole day
As I need some RSS feeds for my everyday job (support forums, issue tracking, etc), and I always have Outlook opened, having a RSS reader that plugged into Outlook looked like a good idea.
My previous experience with Newsgator was that it slowed down Outlook and as I wanted something lightweight (and if possible, free), I did some googling and found RSS Popper.
It worked great for me. The UI is very basic but it does what it should.
