Techcrunch reported that Kevin Rose of Digg announced that Digg will adopt the OpenID system, following what AOL and Microsoft did.

But how does OpenID works? From the OpenID homepage, it is stated:

To login to an OpenID-enabled website (even one you’ve never been to before), just type your OpenID URI. The website will then redirect you to your OpenID Provider to login using whatever credentials it requires. Once authenticated, your OpenID provider will send you back to the website with the necessary credentials to log you in. By using Strong Authentication where needed, the OpenID Framework can be used for all types of transactions, both extending the use of pure single-sign-on as well as the sensitivity of data shared.

I think, it’s similar to the Microsoft’s Network implemented to all MSN’s sites.

ShoeMoney gave us five (5) reasons why OpenID rocks and six (6) reasons why it sucks.

But what made me think is, if it is good to implement the OpenID system to this blog….
