I have been an avid user of Netvibes since Tariq Krim, its founder showed it to me in Paris a month ago. Using Netvibes I came accross the whole culture of RSS feeds and OPML files. Basically an RSS feed is distilled content from a web site as seen in another website, it´s pure text content without the graphics. An OPML file is a collection of RSS feeds. Thus if you and I exchange OPML files you will get my collection of RSS feeds and I will get yours. I already did this with Lance Knobel for example and through him I learned about many interesting new interesting feeds. Looking at this new environment two opportunities come to mind. The first one is adding graphics to RSS feeds. Graphics say a lot about a site, when I am deprived of graphics I am deprived of information. The second idea is to start an OPML exchange where people on the net exchange OPML files basically revealing their reading preferences to each other.
