Best free telephone number search engine
I know this freebie won't be for everyone but it works well for me. I got tired of trying to do a google search of phone numbers only to get pages of useless search results - most of which end up with an advertisment to some pay service. But I've used http://tnid.us/ for free for a couple months now and the results have actually been pretty good.
If someone has a better or comparable free service they know of please share a link.
