Is Foursquare considered a game?

Foursquare is a social utility before anything else. The goal of foursquare is to make things that make cities easier to use and we leverage game mechanics to help users in that stead. Social utility first, game second.

Why does Foursquare only show the initial for last names?

I don't have any special information but a guess would be because of the privacy concerns that come up with making location information public.

One vague reference to this can be found in this article:

You guys set it up so when you become friends with someone on the service you give that person access to their phone number and e-mail address. Have you been getting a lot of feedback from people who would rather keep the messaging limited to just the app?

Crowley: This was by design. The service is designed to make social coordination easier and better, and having the ability to text or call someone is a big part of this. We didn't do a very good job explaining this to users (we were so rushed pre-SXSW) so there was a little pushback from users, but ultimately I think people are cool with it.

With a lot of social-networking services, there's no consequence to having a ton of friends, and I think people get used to that 'I'll be friends with everyone' mentality. We saw this with Dodgeball too. We had an influx of users who were previously on Friendster and friended everyone in sight, and then had a 'wait, these people know where I am!?' moment and then reconsidered who they became 'friends' with. I think we're seeing the same type of 're-valuation' with Foursquare, and I think that's a good thing.

But that's hardly conclusive.

How many people use Foursquare?

To get today's answer, go to http://foursquare.com/user/-240000 and change the trailing number to your best guess.  You must use "The Price Is Right" algorithm: you can guess right and be under, but if you go over the answer, you will be redirected to their home page.

What does Google think of Foursquare?

It's hard to say since they haven't publicly said much and they are a big company so its hard to generalize about individual employee's perspectives, but one thing is: Google launched a fairly similar product called Latitude in the last few months which indicates that they think the location broadcasting space is valuable or at least interesting.
