How about R Wiki entries also?  The enormous advantage of a Wiki is that 
anyone can make contributions, subject to moderation when things get 
extreme.  I'd like to see copies of all the CRAN Task Views ported to 
the R Wiki, with emails sent to the maintainers of all the packages 
mentioned, inviting updates, comparisons, clarifications, 
amplifications, etc.  Similarly, I'd like to see people posting 
questions to R Wiki accompanied by a post to R-Help.  Then someone else 
would edit the question with an answer.  Officially designated R Wiki 
editors could notify people whose posts seem inappropriate for whatever 
reason that their entries may be removed unless clarified, etc.  With 
the right selection of "editors" and a little time, I think the R Wiki 
could become the most valuable documentation available on R.
