Yes, but it will ultimately be one factor of many. More important is yet more experience, connections, and being able to do what the employer needs you to do in a timely fashion.

So use what you created and try and get quoted about it, make as many connections as you can, and get some more professional portfolio items. This will, however, be a great thing to bring up in an interview when they talk about challenging or interesting applications you've built.

It seems like you just put it in an iframe and register in on facebook. I don't think this is worth mentioning. But of course, if the hiring manager is non-programing person,then it will be a big plus.
