Why hesitate?

Among Japan’s major newspapers, Yomiuri, Asahi, and Nikkei, I could not find any XML or RSS guidances in their respective top pages, whereas it is so easy with nytimes.  

On the other hand, both my.yahoo.co.jp (my yahoo) and Google ( personalized page ) make it easy to add Asahi and Nikkei feeds in their RSS feeds readers.  This morning, I found it very hard to add asahi and nikkei feeds into my netvibes.com, which I have been using since then.  Finally I was able to add them only after I googled (for example) “nikkei rss.”  Why would the Japanese newspapers hesitate to promote RSS feeds?
