well, for one thing, it helped me out of my d3pression, it helped me get my art out there, helped me start a business, helped me be creative with stuff, and helped me find new hobbie like cooking and art :)
and plus, it doesnt really affect anything to your personnaly, other than show you stuff you might like depending on things you look up (pets, cooking, etc)
its a trusted site cuz it is. its not bad or anything, but still it does track stuff. for example, lets say your friend just told you they are gonna have a baby. cool right? then when you go on google itll show you a bunch of reccomended dipers, or baby food. it just does spammy things like that.
also good for you for using data
