It was quite a year of mistakes, with Carol Bartz leaving Yahoo, HP trying once again to re-orient itself and hiring ex-California gubernatorial candidate Meg Whitman. On top of this comes various reports that once again email is dead or dying (this could be a tedious repetition of the "year of the LAN" that we went through in the 1990s, even though email has been incorporated at the main notification mechanism of just about every piece of corporate software). But there were some spectacular enterprise Web blunders of the year that we've seen that are worth noting here.
