What is so upsetting about the Millennium Bridge is not that it is swaying - unpredictable behaviour is a risk with any novel system - but that it is so mean.
The width of the bridge - which appears to be about 4m - is narrower than many central London pavements. This bridge is therefore going to make minimal difference to the pedestrian permeability of that part of London. At peak times it will be positively overcrowded - witness the opening on 10 June. Also, at a time when sustainability reigns supreme, why are there no cycleways?
As part of their deliberations on possible damping solutions may I suggest that the design team considers widening the bridge deck or adding cycle tracks, or preferably both.
