Indeed, it is a bit weird. Note: This was no exhaustive search for job skills, I think that deserves a single post, with well... proper data and fancy graphs (preferably made in R).
I am sure there are new data science startups looking for R-magicians. No doubt some of the best use it, as seen in this slideshow by Xavier Conort (10 R packages to win Kaggle competitions): http://fr.slideshare.net/DataRobot/final-10-r-xc-36610234
On another point I understand the startup community is dominated by hackers with the standard programming tool box like C, Python, Java, et al. So I believe there is still opportunity.
