Google just launched their new +1 service which allows you to "publicly give something your stamp of approval". Or in Facebook terms, "like" it. Right now it's still part of Google Labs and you have to opt-in to try it out, which you can do here. I gave it a spin today and there are some cool and not-so-cool things about it. It all depends on how comfortable you are having your name publicly associated with the links you choose to endorse. And "endorse" is a good word since your +1's can be used in Google Ads. So it's important to have your Google Profile set up with the right privacy settings so that you can make sure your Picasa Web Albums and the like aren't available to just anyone. That said, I like that once you've opted in, you'll have a new tab on your Google Profile keeping track of all the links you've +1'd along the way. Do we say +1'd now instead of "liked"? So hard to keep up. You can choose to make your tab public or not, but either way it's a nice handy list to refer back to:
The video below will tell you a bit more about how it works and you can read more about it on Google's +1 Page. Tell us what you think about +1 in the comments section.
