I'm a matured adult in my 50's. is myspace just for young kids?

Haha. Your ok, sweetie. There are lots of older people on that site. Just browse for the people in your age category and you'll see. Myspace was originally for adults and the lowest age I believe at that time was 16. Now its 14 and older. You will run into stupid kids that will say you are too old to be on there, but they have no clue about anything really.
