I am an active user of Mathematica and “R”. I find blog posts from a variety of sources very helpful in learning both systems. There is a site for R users called “R Bloggers” that syndicates the content for everyone in the R community. No such site exists for the Matheamtica community making it harder to find posts with interesting application of Mathematica. Is this something Wolfram would take on or is a capable member of the Mathematica community going to have to volunteer to do this?
There was/is an attempt to create a blog that goes along http://mathematica.stackexchange.com/ , but unfortunately it hasn’t yet picked up momentum.
It is not a syndicating site, but it is a blog that is open to anyone who can contribute good content.
