With the internet growing everyday and blogging becoming more of a facet of todays internet I think it owuld be a great feature to have the ability to post data from all modules that would like the ability to Social Networking sites like digg, delicious, technorati, etc... If this was added to the core there could be a core module that would allow the admin to either add/remove Social networking buttons site wide and maybe even allow the other modules to override them settings based on the development of that module. This would allow users site to get more traffic which in the end would also increase the seo aspect of the users site. I have seen other cms apps out there that have such a module like wordpress and drupal to name a few. Here is a link to a demo of a jquery script that will build a show/hid option for each of the buttons added and I am sure there are many other ways this can be done, but the main thing to get across is this would be a very nice feature for us all.
