If the Dr is in, it is time to close this thread along with 2008 (which was actually a good year for me, go figure).
Vicky is the winner, and perhaps Dr. Misra as well, since he used the correct spelling in his question headline.
"e-government" - because of AP Style, because without a hyphen it may be a typo, because we don't shorten words in proper usage, and because there is no justification for capitalizing the G. Also, Government 2.0 is indeed a different animal, referring to something other than the simple adoption of electronic tools by government.
I believe that in the tradition of this forum thread, Vicky will judge the next contest. And having seen Dr Misra's Internet quiz, I know there is plenty of fun in store. On to 2009!
