Sometimes you just need to know a little bit more information about the site you're looking at. Maybe you're trying to decide if it's trustworthy, or maybe you're just a little bit (or too) curious. Well in any event, if you're looking to snoop, check out GreatDB. Punching in a URL into GreatDB will bring back most of the following information: Whois, Site Age, Blacklisting Status, Language, Web Host, Ping Time, Pagerank, Alexa Rank, Backlinks, Search Engine Indexes, DMOZ Listings, Wayback Entries, Top 5 Keywords, Domain Extension Availability, and a Preview Image. Not bad considering all it takes is about 20 seconds of your time.
Probably the creepiest data point on the list is web host, which could be used nefariously to prey on hosting companies with weak security. But everything on the list is information that is publicly available if you know where to look, so it's hard to take issue with any of them.
