I have begun to list great websites and tools for journalists. Please send in your ideas. Thanks!
Find news, conversations, trends
Happn – Twitter trends and feeds by city.
Internet Archive’s Wayback Machine – An archive of more than 150 billion web pages that have been deleted from their original sites.
Pipl – Search for information about interview subjects and others. Pipl retrieves information from the so-called “invisible web,” or “deep web,” which does not always immediately show up in Google searches.
Zabasearch – Another people search engine that looks for information from databases that Google crawlers miss.
Networked Solution’s WHOIS – A great way to find out who is behind a domain.
