According to Konfabulator, the acquisition also marks the formal launch of Yahoo's Developer Network.
"Since we're kick-starting Yahoo's Developer Network, this means our current Konfabulator community will become the founding members of Yahoo's Developer community," according to a posting on Konfabulator's site.
