Charlie had one of those posts yesterday that created an “ah-ha” moment for me. He wrote about the value of Foursquare as being something more than a game.

Go read the full post here.

Fred was also inspired and he joined.

I did as well. Here’s my foursquare profile.

After I joined, Charlie tossed up this gem on twitter:

Uh-oh. I created a monster with my 4[] post ( and now all these old dudes are friending me. Oh wait… it’s just @bijan

Still trying to get over that one.

In any case, I’m looking forward to diving into the Foursquare pool. The iphone app gives you control over what goes out over twitter and what doesn’t which is how I hoped it would work.

It’s going to come in handy for our upcoming vacation to Cape Cod next month. My good friend is going to the Cape a few weeks after us. He asked me for restaurant & beach recommendations. I just sent him a note telling him to join Foursquare and then he’s see all of my favorite spots along the outer cape. This friend isn’t into Facebook but he joined Foursquare a few minutes later.

That tells me something.

And as I mentioned in the comments on Fred’s post, if Tumblarity is any indication, I think we are going to see a bit of healthy competition between a few of my unnamed friends about Foursquare rank & status

Should be fun and helpful too.
