I like OpenID[1] although I think it’s more complex than most people can handle — and that’s a big hurdle. OpenID gives visitors to your blog or web site a chance to log in (create an account on your site) using their login information from a participating OpenID web site (like gmail). In other words, they don’t have to create a separate account at your blog – they just reuse their Yahoo (or gmail or other[2]) account. In theory this should make it easier to remember account names and passwords because you just use one account to log in at many sites.Ever since OpenID was announced (2005) I’ve loved the idea. There are OpenID providers, and then there are other sites that allow users to utilize OpenID for the creation of accounts.
