Wikispaces, the wiki creation tool, is the latest to add OpenID support.
This of course means that new users that have an OpenID URL can more easily sign up for Wikispaces. The open system that OpenID has created is rather appealing to Wikispaces, and the site is joining the likes of WordPress, AOL, 37Signals, WetPaint, Microsoft, Afeeda with its new integration of OpenID. Adoption for OpenID has been picking up for integrated online tools, including Plaxo, which has added OpenID support for its 3.0 version, to be released later this year.
