I've been looking at RSS readers lately. Evryone with a blog needs a constant source of new ideas to write about. And you need to stay abreast of what the blogosphere is talking about in your niche. There is no better way to accomplish this than RSS and an RSS reader. I plan to do a blogging 101 post soon surveying the best RSS readers and as a result have been looking at several.
If you have a Mac then you already have the best RSS reader: Safari. The ability to click on the little RSS icon in the address bar and then add the feed to the folder of your choice is really convienient. I understand that IE7 will have a built-in RSS reader. Personally, I think the best place for the RSS reader is right in the browser.
I also use NetNewsWire (from the NewsGator people) and I like it a lot.
I've been playing with Google's new reader and I have to say that I am impressed. Having your feed reader on the web is not quite as seamless as having it integrated into your browser, but it's getting there. Particularly since many blogs (like this one) display a little icon allowing you to add their RSS feed to your Google reader with a single click. (If you have a blog, you need to get a free Feedburner subscription so you can do this too.)
