Technology Questions

[zsayeed]

I have some technology questions for you. I need your help. Can you please post your thoughts?

1. What technology does facebook use to to consolidate across web pages for the like button and share button?

2. Is there any other alternative to the facebook method that is picking up in industry?

3. Do you see this consolidation coming up in any other sectors other than social media?

4. Does html5 do anything for identity consolidation?

Thanks for your help.
