Which people search engines do you use?
The first four in the list below are my favorites. One extra criteria for me, in addition to getting good info, is convenient and friendly user interface.
- ZoomInfo
- Jigsaw
- Pipl
- Tweepz (for Twitter)
- www.peekyou.com
- http://wink.com
- www.123people.com
- www.zabasearch.com
- http://people.yahoo.com
- www.spokeo.com
I also X-ray spoke.com, looking for email addresses, and X-ray LinkedIn. (You will find custom search engines implemented by X-raying those sites under the links.)
