Reasons why Reading.am is already great:
concept of hooks, with some predefined (send to Twitter, Pinboard, etc.) and some readers can define for themselves by specifying a URL.
recognizes that some people have multiple Twitter accounts
personal dashboard RSS feed. That is, an RSS feed of what the people you are following are reading.
Some ideas for Reading.am
Show the full chain.
if I read something because of Max Fenton, and he read it because of Nicole Jones, show the whole chain. Maybe it's a network?!
When posting to Twitter, add "via @sillygwailo" (or "b/c of"?) to the end of the tweet. Since you can add multiple Twitter accounts, make a setting for each user to specify which account to use when credited.
some other way to notify that someone read an article because of you. Email?
rel="nofollow" on "Nope" links, at least for the logged-out version of pages.
I have a hard time with the radical transparency inherent in the app, so I'd like for setting a delay before something appears on my reading list (and RSS feeds, sent to Twitter, etc.).
Maybe I regret going through the reading.am URL to look at something, or pressed the extension button by mistake
I would say make this a setting in preferences, with a maximum of 60 seconds so that there's still some real-timeyness to it.
it should probably show on your reading list, with a background colour or box around it to suggest 'unpublished', with maybe a countdown clock. The countdown starts from when you click through an item or click the extension's button, not when you first think to remove it from your reading list
