I don't think that this would affect me greatly. Yes my mood does change but I don't mind too much. Most people can tell my moods anyway so this wouldn't make a difference.
This is a good idea, but I would make changes. For the name section I would only put my first name and thats it. I would not have my entire name, my age, the suburb/town/country I live in or the amount of friends I have. The stuff I would have would be my first name, my mood and my relationship status. That way no one could search my name and find me easily.
This idea would make introductions easier as you would know others who has the same interests as you and who has the opposite interests. It could also help with people who are really shy, or sad or left out quite a lot as people would recognize it and then either include them or cheer them up.
This would make my day to day life more exposed. Like, I wouldn't be able to hide my emotions out in public. Sometimes you go for a walk or something to clear your head but with this, you're going to have people (who actually care) coming up to you and asking if you're okay and stuff like that.
