Really Simply Syndicate Anything | rssa.at. Quickly and easily create an RSS feed for
your website. Then use that feed to share your content with other
people and applications all over the web (and if you like, even to
power your Twitter updates).
Add the rssa.at alerts widget to a page you’ve created a feed for,
and let your users sign up to receive email alerts when you publish new
content. Copy and paste a quick bit of widget code to embed a signup
form directly into your site.
Feedmysearch. allows you to turn a Google search into an RSS search. Nothing new in that of course, since you can do that at Google anyway, but this makes things a little bit easier and gives you a lot of different ways in which you can save your search - to Pageflakes, Bloglines and so on.
