Share contact info, social graph via Google Profiles

In another expansion of its Profiles site, Google has enabled people to share their impinging information with selected contacts, a move that offers modest privy for users of the service and valuable data to Google.

The feature shows as a "C ontact info" tab; clicking on it shows whatever contact information you've entered and the note, "You are not sharing your contact information with anyone. Edit your profile to state contact info, and then decide who to share it with so that they always have the most up-to-date information."

Google Profiles is hardly a Facebook crusher or a LinkedIn slayer, but it is getting gradually more elaborate, as Google builds it up. In October, user profiles became visible to search engines. In Nov came identity authentication and a mechanism to let people contact you w ithout sharing your e-mail address.

Here's why this Profiles move is interesting: telling Google whom you entrust with your personal information is a good way of identifying the close members of your social circle--in other words, the strong links in your social graph.

One of my constant complaints with services such as Facebook, LinkedIn, and now Yahoo Open Strategy is that it's hard to sift the activity from my close contacts out from that of the ocean of second-tier people. If Google wants to make something bigger out of its Profiles work, a list of your close ties is invaluable data.

It indicates whom gets your trust, whose e-mail you want to read first, the people with whom you're staying in speck, and those likely with shared interests. Even better for Google, by labeling data as "family," "co-workers," and your own mailin g-list groups, Google can discern subtler distinctions in your social-graph ties.

When you're travel your personal information--phone numbers, instant-messaging nicknames, addresses, and your birthday--Google presents options for sharing with va rious people. For me, it presented checkboxes (unchecked by default) next to the Gmail lists I've alter up.

The page also has two course for setting up groups for family or co-workers. Clicking either presents a list of your top Gmail contacts.

I could see some tighter integration with Gmail's contacts function here. Google is revamping Gmail contacts (hurrah!), and using Google Profiles would be a great way to ease the constant pain of kee ping your contact listing up-to-date.
