Popular widget enabling program, Konfabulator, has been bought out by Yahoo.  According to the Konfabulator home page, the name of the program will slowly be changed to "Yahoo! Widgets".  The name "Konfabulator" will slowly be retired.  For widget enthusiasts, it means that users will no longer have to pay to register Konfabulator.  Users who paid for Konfabulator in the past couple of months will receive refunds.
