Most new software ideas were pretty obvious ages ago, there are just so many barriers to usefulness that have to bridged, some small like how can I quickly bookmark a bunch of useful pages with Del.ici.ous and then get them to pop up well-formatted and user friendly in an Economist or Huffington Post-like front page (repurposing, if you will, and what I am doing this morning), other barriers are gigantic like how can you get the content of a successful paper publication to generate as much revenue in a web publication format. That’s a question that everyone is struggling to figure out and people eventually will, slowly but surely.
