A good RSS reader for sites
Google Sites are an incredible powerful tool, and the extensibility of "insert -> gadget" is fantastic.
But... I still get frustrated that the gallery of gadgets is so vast without a great way to find the nuggets.
So, in case you are looking for a good way to display your favourite RSS feed (only one) in a Google site, I found this one to work well for me. Just copy the URL, and paste it in "gadget URL".
What makes this one good for me, is that it's not trying to be too clever and format my content. It simply inherits the style from the site it's sitting in.
