A good post today in Read Write Web: We would have to agree that productivity is key. However, extensibility is also right up there at the top of the list. Start pages and environments that utilize widgets should be agnostic with regard to the applications ("modules" and "widgets") that are running on them and from where they are running. This gives users and developers the greatest amount of flexibility in terms of enhancing the productivity and usefulness of these sites.
Our site, www.whiteboxresearch.com (in beta), is geared for stock analyst user types who what to perform equity research using a market driven financial model as well as converse about stocks in near real time through posting to their blogs and reading RSS feeds all without leaving the site. Our goal is to provide the ultimate in extensibility for our users. Our site can also be customized with applications using our mini-api by permitting a user to enter a URL and then having that site as a module in Whitebox Research. We also allow the development of sites/applications that sit on/run from developer or partner sites that provide greater flexibility and productive apps in a "module" or "widget" format within the context of your Whitebox Research start page...for example a real-time ticker, or perhaps a trading application.
