I got my own theory, when i started programming, i was writing all the code by myself, just to understand all, but when it comes to write n-th time datepicer, or so, i use my old code, or download some new fancy good working code just to save my time, cuz i exactly know how it works. I dont get it bad to do so, as long, as you are good to write all this things by yourself :D But it can be true than in lack of skill someone can just google "awsome stuff doing source code" and use it, is this bad ? Its bad for programmer, who wont learn how to do it, but its $$ for company that save time.
