I never would have thought that the perfect RSS aggregator would come from what is basically Microsoft. RSS Bandit is a SourceForge project but the main members are some of Microsoft's top .Net developers. What's so good about it? Here's the two features that make it a killer app: the ability to store “the current state of search folders, flagged items, replied items, subscribed feeds and read/unread messages” using WebDAV, FTP, or a file share; being able to have it use a browser other than IE to open links from the feed summaries/articles.
Since I use my RSS reader at work and at home, I find myself manually trying to synch them up. Oh, sure, I could have used a web-based aggregator but I didn't want to. Don't ask me why, I just didn't. Well, now that I think about it there is a reason: some things are just better as desktop apps and feed readers are one of them. Being able to store my feeds and state on an FTP server is an ideal solution to this. I host web sites for a living so FTP access is easy. Even if I didn't, I could use the FTP access to my (shameless plug coming in 3, 2, 1 …) Blogware blog to store the settings file.
I've been using FeedDemon for about 6-8 months and it is a very good product for which Nick should be commended (and by commended I mean don't steal his software you cheap bastards!). My only complaint was that it uses IE as its browser and that can't be changed. Since I don't like using IE unless I have to, this always bothered me and I was doing way too much copying and pasting of links from FeedDemon to Firefox. RSS Bandit allows you to either set it to use IE, use the default browser for your system, or use an executable. For me, I set it to use my default which is Firefox and I love it. Couple this with Privoxy and I feel much better about browsing the sites linked to from a lot of the feeds I read.
