Following up on my Newsvine story, I found this post interesting and had to agree on the findings. I grow tired of Digg and Reddit (as well as Slashdot) pretty quick, while Del.icio.us feels like it will have longer legs.
Why Reddit, Digg, will not succeed with main street audience and Del.icio.us will.
Why does someone tag something on del.icio.us? Because users want to save it for personal reference. What’s the psychology for other news aggregators? I think this is cool and I will share it with others in hopes of karma whoring.
