Tonight’s Mac Help Radio (9:00 -11:00 PM ET) features Dan Wood of Karelia Software, maker of Watson, who will be announcing some new features for the popular application. The show will also feature Tom Yeager, columnist for InfoWorld magazine, who wrote about something that Mac users have believed for years — that Macs have a serious shot in IT departments. Finally, there will be an interview with Dave Ottalini of the Washington Apple Pi User Group, which is not only having its annual sale, but is also celebrating it’s 25th anniversary.
