What does it mean that Mary Meeker has a 21-page research report hailing RSS as a Very Big Deal? 

She cites three key things: “1) rising usage of RSS (Really Simple
Syndication) by content providers as a standard distribution platform
for online content; 2) 2) ramp in the creation of blogs and other
user-generated content; and 3) Yahoo!’s easy-to-use integration of RSS
feeds (including blogs) that was rolled out in beta to its distribution
channel of 25MM+ My Yahoo! users in late September.”  I think
she’s right about it redounding to Yahoo!’s benefit to some
extent.  But of greater interest seems to be a) the next
generation things that can be done with RSS and b) the social
implications (i.e., how it will affect how we get and interact with
information — text, audio, video, whatever — online).
