I don’t think I would (even if I had a phone to support it), though I’ve just been steadily growing more and more wearry of the amount of information I give google about myself. Its never smart to put all your eggs in one basket.

Do you use it?

I agree with you, but don’t you think what you are saying can be applied to the release of almost any product to a certain extent at least? I mean with every new development in regards to technology the “we need to be weary” sentence seems to come up. To be honest I expected Turtlethink to consider a “new” reactionary response to the release of yet another social connectivity tool to hit the market, but I guess tradition isn’t so far behind us after all.

I’ve been using it with two of my friends and I would say it is not creepy. To be honest, I knew where they were pretty much all the time anyways, because they are avid twitterers anyways. So really, what with facebook, twitter, etc, it is really not that much of a change. You can turn it off any time and it just says “unknown location.” Mostly it shows me sitting at home I have yet to see whether I find it interesting or useful to know where my buddies are. We shall see in a few weeks.

Ach! It screwed up my emoticon. The frown was supposed to be in response to me sitting at home all the time.
