Media organisations could encourage journalists to embrace new ways of working by making it easy for them.
For example, articles can frequently benefit from the inclusion of related links. One method of getting those links to readers would be to create a del.icio.us account and direct readers to it.
But a simpler method would be simply to input them with the story itself. This would also allow the business to make better use of them, as the links would be associated both with an individual journalist and with a specific story, as well as being stored on the organisation's own servers. (Links from a journalist's del.icio.us account can be accessed as an RSS feed but I think it would be technically difficult to associate the right links with the right stories this way).
One of the obstacles to journalists doing this is frequently the content management system they use, which may not be designed to accomplish what the media organisation is trying to do.
Media businesses should take the initiative and develop systems designed to make it easy for staff to achieve what they want them to achieve.
I also believe that, while it makes sense to use whatever applications and web services are out there for the taking, it would be a mistake to rely on them. We should deciding what we want to do and then doing it - inspired by what other people are doing, rather than depending on them.
Below is a dummy front end (for authors) of a content management system which I think would be easy to use and accomplish some of what a multimedia news organisation should be trying to accomplish.The front end is a vital part of any CMS, but a small one. And what is below is only for illustration - it doesn't work. And it is probably missing things. It's simply an attempt to illustrate what I mean when I talk about making it easy.
