Thank you very much for this nice article.
In my quest of being unhosted, I discovered NewsBlur (http://www.newsblur.com) which is my current choice. It also has very nice features, specially for tagging, sorting and prioritizing feeds and articles. It is actively maintained by a kind dev, written in Python, uses JQuery for UI, MongoDB (or Pg) for storage and Celery/RabbitMQ for feed fetching and parsing.
Really the only thing I miss compared to Google Reader is the shared feed which I hope will come soon. May be just after the release of the soon to come iOS app
