Since social networks have become so popular, they have also become very useful for sourcers. As many of us know, one can do quite a bit simply using the Google site: command with a number of those sites - the ones that have profiles available for indexing by search engines.
inurl:in OR inurl:pub site:linkedin.com [keywords] example: inurl:in OR inurl:pub site:linkedin.com cisco engineer
What are some other sites and search strings you have used? I am especially interested to hear about lesser-known sites, social networks in particular, and creative strings that work with them.
It is also good to understand how much you actually find with those strings. Say, with Linkedin you only see "public" profiles when you search via Google.
