Since Facebook’s announcement of the Open Graph Protocol and Graph API at the f8 conference a few weeks ago it has been time to re-read the Facebook Documentation and try to work out how the new API’s fit into a few personal and work projects.

As part of that research I decided to fill a void in my development time – I’m forever trying to find the Facebook User ID of the user I am currently logged in as – and it doesn’t help when you have 10+ testing accounts, plus my own personal account. So I threw together this: allows you to login (Using the Facebook OpenGraph API) and it will immediately show you your current Facebook User ID, you can logout and login again with a different account and it will do the same for that one.

No personal data is collected or stored during the process – it simply looks up your User ID and shows it on the page.

Over time I will add some more features, the ability to see your Friends User ID’s perhaps and some other cool things that will help developers.

Hope some people find it useful!
