I have previously written that Delicious search is one of the best ways of searching for things when a standard search doesnâ€™t pull up what you are looking for. After Google, it is my favorite â€œsearch engine.â€ Adding this information into Yahoo search is a great idea. Google could leverage the activity of Delicious users to improve its search results, or at least give users an additional place to find content. Mine the tags to provide more context and connections among pages. Note that Google, and Bing, are exploring different ways to apply social signals from Twitter and Facebook. Inclusion of Delicious in the search process would be consistent with that. And Google would still benefit from its Adwords program here. Which would be a monetization strategy for Delicious, which has no ads.
