I've been playing with Feed-Me.Info for the past coupple of days, and I've been particularly impressed.
Feed-Me is a web-based news aggregator which collects feeds and places them in linear format (aka newspaper format) for easy reading. A few features include:
1) The ability to bookmark, e-mail, and print posts directly from the aggregator.
2) I think that this aggregator has the abillity to highlight keywords within the feeds display, which is really impressive.
3) The interface is user friendly, once you get used to it. It took a bit of negotiation, but once I figured it out, it was a piece of cake.
4) One can view the posts by date, so if you missed a few days of RSS reading, you can go back.
5) Its Free!!
6) OPML imports!!
7) Feeds are automatically updated every hour.
8) You can place feeds into hierarchical folders, so that if you do work for two different projects and if you want to keep the content separate, you can.
I do have a wishlist:
1) The ability to delete posts
2) The ability to publish directly to my weblog from the aggregator (this can be done by implementing Blogger API (I think)
3) Integration of my POP3 e-mail into the aggregator (although I'm still not sure if this is a good idea, but the option should be there)
4) An RSS Feed for the site news page.
Feed-Me is still in beta, and looks like another viable choice for using a web based aggregator. As I have said in the past, I believe that the future of aggregation software is web-based. Since Feed-Me is free, and if it gains more popularity, the server will start to get overloaded and slow down. This is where fee-based aggregators can come into play. If it has everything I need, and I can be assured of no 'slow' time, then I might consider paying for it (an annual fee perhaps). I mean, I pay for Radio now ($40 per year) and it is well worth it to me because it does everything I want...I'll continue playing with Feed-Me and see how the development goes.
