Scopus & ISI competition is good for the market

Today Thomson Scientific announced a new feature for author identification. I was wondering why it took so long for Thomson Scientific to find a solution for author disambiguity issue. Is it the Scopus pressure? Whatever it is the users will definetly benefit from this competition and the enhancements that both product groups will introduce in the future. In terms of future, it will be interesting to see how Google Scholar and Live Academic will use CrossRef and figure out to provide better cited reference searches and how Scopus and Thomson Scientific will compete with Google and Microsoft. One unanswered question here is that we don't know how serious Microsoft and Google are in providing services to scientific and engineering community.
