Well, you can try sites like lenta.ru or rbc.ru, but they are regular news sites. I don't know any of them which use simpler language. There are youtube videos with subtitles, movies and podcasts in Russian. I often read blogs at livejournal.com, many interesting people write there. But this content is in 99% cases written by native speakers for people who are fluent in Russian. The only sites with easier texts I know of, are language course sites.
