In response to Jess about an RSS site merging the news from others...
If you're bored, look at the Moreover science news aggregators. They produce the top 15 stories on particular topics, every 15 minutes (for free - if you want more, you have to pay). Now, set your RSS reader up to fetch these every 15 minutes. What you'll see is that 'real' stories are buried because every bloody news site under the sun is regurgitating the same story again and again, usually word for word from a press release or Associated Press article (or press conference, or space.com, or whatever happens to be the predominant source for that subject area).
After the 8th article with exactly the same summary and (when viewed) identical content, you begin to wonder why you're bothering with automatic syndication. Sometimes it works. For 'important' events such as the Columbia disaster, or 9/11 the articles are usually varied because people want to make themselves read, but for small stories - Beagle 2 is a good example - you just get the same thing thrown back at you.
Within such a small subject area as RISC OS there's only so much you can say. And it's very obvious from Iconbar's RSS feed that you might as well just ignore them and make sure you read Drobe and csa.announce irregularly. Whilst RSS is intended for syndication, it's a whole lot easier to manage it yourself than to have someone else determine the stories and the relevance.
Remember, it's not just 'news' sites that produce RSS feeds. There are RSS feeds for projects (q.v. SourceForce) and other sources of RSS that are important (to some) but not to others.
