Just received this quick tip from a user of ours who was trying to find a way to see if any of their Facebook friends are on Google+ without having to ask them individually. This method assumes that your friends use the same email address for both Facebook and Google logins.
1 ) Go to http://address.yahoo.com sign in or make an account
2) Import Facebook contacts to Yahoo and export those contacts into an CSV file
3) Import the CSV file into Google Contacts
4) Head to your Circle page and go to “Find and Invite”
5) People you know already registered to Google+ will show up
This will also work with Microsoft’s Live/Hotmail platform. It’s interesting to know that Facebook blocks the use of a certain Google Chrome plugin that automates this functionality without having to sign into a different email network and without having to download files. Facebook says they don’t believe users should be granted access to their friends’ email addresses if they aren’t publicly available on that user’s profile.
Noble, but as our tipster points out, Yahoo and Microsoft should both be without the functionality if this is truly the case. Sounds to me like someone’s trying to prevent folks from importing their friends to Google in fear that they may use Google+ and, get this, actually like it more than Facebook. Well, another announcement made this morning suggests that much, anyway. [Thanks Kawang!]
