I have found myself using Google Documents more and more over the last few months.
One of the areas that was severely lacking was the ability to share parts of that content.
That is all changed now with Google Gadgets.
For example, for my training I had resorted to n HTML table on my training page https://rossgoodman.com/fundraising/training/ whilst not difficult it is not exactly elegant.
Now I am recording my times in a Google spreadsheet and using two gadgets, one to show a tabular list if the data and another to show an interactive time series chart, the same as is used on google finance.
Cool Huh !
