Facebook Applications, How Did you Take it?

I am addicting to Facebook social networking just like Friendster before. But I am no to applications! Aright, some of them but in general I do not really like it. If you are one of my friends in Facebook (and am sorry if you are not), you can see my profile so clean from it. One day, actually just days ago, I have something I like to which I press the button "like" which I confirm that word speaks to what I felt. But it did not occur to my mind that once I press it, it will also tell that such application could get my personal information just like my book of friends and any others which could tell what I write in there. I can tell because I inspect my privacy settings just last night. Time to time I am looking at it (and I expect you also, if not then you have to) because time to time there are also changes on Facebook. And that is not bad but you have to be aware which for sure it is on Facebook rules and regulations (or something like that) which many users just neglect it. You have to know you should not neglect it especially if you are liking something, allow applications to have it (which I seldom allow one). With "like" only one application I observed (well, everyone should have to be observant) which got my personal grants which mean, allowing them to write on my friends wall and many others which I urge you to see your privacy settings now and see if you have grant them and you can change it now if you do not like, you forgot to check it, or you have not cared for because it really is essential if you take Facebook seriously, which it should have to be.
