      teamGoogle properties (such as Google Personalized
      Homepage, Google Desktop, etc.) used to be the only places you could add Google Gadgets, but
      not anymore! You can now easily add gadgets to your own site for free by browsing the
      directory of 
gadgets for your web page, selecting a gadget,
      and copying/pasting a small snippet of auto-generated HTML. For developers, this means
      significantly increased gadget distribution across the web, forums and blogs.
The v1.0 launch is a work-in-progress with bug fixes lined up and ready to go
      -- 
gadget settings page fixes shipped last week, and
      our engineers are working feverishly to fix CSS-related rendering glitches. Extending support
      for sites that are blocking IFrame and Script tags may take some time, but it's definitely on
      our todo list.
Google Gadgets for the whole web has a few limitations,
      which gadget authors should be aware of when writing gadgets for third-party webpages. To
      ensure that your gadget will support distribution across the web, take note of these important
      facts:
-  Make sure your gadget supports 200-pixel content widths
      for placement on third-party web pages. While Google Personalized Homepage gadgets have an
      average width of 250 pixels, assume third-party web pages will have even smaller widths.
      Otherwise, you may start receiving complaint emails about annoying horizontal scroll bars.
      
 -  You cannot store data or state for gadgets embedded on third-party web
      pages. If your gadget contains code to do so, it will silently fail. 
 - 
      Inlined gadgets cannot be added to third-party web pages, and will not appear in our directory
      of gadgets for your webpage. 
 -  Since
      inlined gadgets are not supported, embedded gadgets cannot modify third-party webpages for
      obvious reasons.
