big fan of feedmail [1] for a "dumb" reader. It just delivers it to your inbox. I have a folder set up called "feed" and I can do all the email things to the items landing in that folder. Every email costs a credit, you can buy 10 000 credits for $10, which works out to $0.001 per article.

The only thing it misses is any sort of highlight saving deal, but for those I just save the article to zotero and annotate it there.
