RSS is Web 2.0 ??

Need to connect any service to another service on the Web (or anywhere else)? Trying to mash together data? Building supply chains? There is generally no need to ever ask anyone to stand up a new web service. Pull everything you need via its RSS feed. Some software developers will disagree with this and say there are better methods, but to this I point out: 1) RSS is robust enough that it's all you'll ever need nine times out of ten and 2) it's what you're going to offered automatically anyway, take it and get something done.

RSS creates the Web 2.0 information ecosystem by enabling interconnectedness, network effects, emergent behavior, and much more as well. And RSS doesn't demand control of the other end of the conversation. This is a big enabler all by itself and is a classic Web 2.0 force. By letting consumers of RSS use any tool or service they want on their side, barriers are eliminated and connectivity is encouraged.

i think this is stretchin RSS a lil bit too much. btw, a del.icio.us survey on what is web 2.0 based on del.icio.us/tag/web2.0 RSS fares pretty low at 2.5%
