As an update to James' post back on Feb 15th, MSN is involved in a "search for charity" campaign in the UK.

The National Society for the Prevention of Cruelty to Children (NSPCC) "will receive a donation every time users carry out an MSN search via www.clickscount.co.uk." Apparently, MSN plans to add more charities in the near future.

There are no details on how much will be donated or what constitutes as a search. Will UK'ers switch over to MSN en masse? Would you? How will this improve the search engine's relevancy?
