It's not so much that they are throwing more bodies, but that for such a high profile web site they are just now bringing in the best and the brightest. Why weren't these people working on this project from the beginning? I don't know that it would have mattered though, as the main problem seems to have been that too much of the requirements were not well defined until too late in t he development cycle. Software projects get delayed all the time, but this one seems to have been pushed out before it was thoroughly tested. My guess is that plenty of people knew this thing was half baked, but that the release date couldn't slip for political reasons.
