This article “Web 2.0: Unsafe At Any Speed?” by Andy Patrizio on internetnews.com argues that many Web 2.0 apps have the potential to be very unsafe, because they aggregate content in mashups via AJAX and iframes. And some of this content (including possibly several generations back up the chain, i.e., aggregations of aggregations of aggregations, etc.) might contain malware code.
I guess this is why WordPress.com does not allow us to put iframes in our blog pages here. In any case, this is certainly something to keep in mind, for those of us pushing adoption of Web 2.0 collaboration tools by enterprises. The article does discuss what some are doing to avoid the problem (e.g. scrubbing code to eliminate “code injection” and avoiding iframes altogether).
