7 April 2016:  Spring Cleaning (every 5-6 years!).  Cleaning up this page ...

Finally took time to update/refresh this list.  The Google Gadget Registry is now long gone - "deprecated" then eliminated with iGoogle in late 2013.  Here's what it looked like in Oct 2013 (via internet Wayback Machine).  The Gadget developer's guide is still alive, but also also dead-ends when it comes to publishing a gadget.  IT is what IT is!

Revisions noted in table below - not many left.  Found the following to play with - will try to add these to this page in next pass:

-- Original -------------------------

The table below contains tagboard/chatterbox tests from the Google Gadget Registry and a few external sites. The list was originally created in June of 2010, so you may want to also visit the directory and search @ http://www.google.com/ig/directory - There are MANY of them.  The collection may help others.

Hmmm?!?  I suppose you should feel free to comment below if you have thoughts or a favorite!     Or drop me a line
