How many of you willing to give gmail/yahoo info to expand the network
colinplamondon: Most people don't care, the privacy implications are only worried about by people who know enough to worry about the privacy implications.Despite the Facebook Beacon blowup in the blog echo chamber, very few users cared:http://www.sawickipedia.com/blog/2007/12/05/facebook-bites-t...So, sure! People who read CodingHorror are concerned about the security issues... but how many of your users even know what the hell CodingHorror is?If your social network is focused on people who might have heard of CodingHorror, you might want to have second thoughts. If not, keep it secure and be careful about your implementation. Personally, if I trust a site then I'll use the address book import if provided.EDIT: Like mentioned above, definitely use Google's actual tool to do the import:http://code.google.com/apis/contacts/
