Google abandoned Wave in August when the company realized that people weren't that into it.
On Friday, Google's Dan Peterson wrote that voting to accept Google Wave into the Apache Software Foundation Incubator "was overwhelmingly positive."
"By my tally," Paterson wrote, "there have been 88 votes over the past 3+ days, including 18 IPMC binding votes, 8 votes by members of the ASF, and no -1 votes. Of those 88 votes, due to a slight process confusion (and an issue of reply-to settings), 22 votes were only registered on the existing wave-protocol Google Group."
Google abandoned Wave in August because people just weren't that into it. The open source version is called "Wave in a Box," perhaps named after the Justin Timberlake's 2006 Saturday Night Live skit.
