Google announced tonight that the new Blogger (nicknamed 'Blogger in Draft') will support OpenID-based commenting. Essentially it means that users of OpenID-enabled services - such as LiveJournal, WordPress and TypeKey - can comment on any Blogger blog using their accounts from those sites, rather than with Blogger/Google accounts.
This is another small but significant step on the way to an open identity system on the Web, something that we here at Read/WriteWeb have been promoting. Incidentally you may be wondering if we will 'eat our own dogfood' and implement OpenID on this blog -- it is in the plan for our big re-design, which is coming very soon!
Thanks David Recordon for the heads up.
