Summly never stuck with me. @bryankchang have you tried it yet? On a related note, @Jason's http://launch.co is similar and according to Twitter as of 20 mins ago (https://twitter.com/Jason/status...), his new startup, Inside.com is launching on 1/23 or 1/24. Lots of movement in the publishing/content space. :)

I prefer @circa for consuming this type of content.
