So, my wife and I (mostly) use Skype chat to share links with each other when the links are only meaningful to us. eg, during a session of buying something, we send links back and forth.
Our current flow, which I don't like, is copy link from url bar -> find skype window -> paste & send
I pulled this slide from a Lucene Revolution presentation: http://www.box.net/shared/in1hpkgdyndxafs7hu06 The presenter and his significant other were looking for a new car to buy and he sent links to her via email and got comments back. This is another use case I am trying to describe.
What tools do you use for such use cases? Mozilla F1 (http://f1.mozillamessaging.com/) seems to be the closest one that integrates nicely with the browser and contact lists but it is more tailored to public sharing. And I guess I am looking for something between email and IM.
