The Internet and social networks like Facebook and Twitter immediately lit up Wednesday night with the news of the death of Apple Chairman Steve Jobs.
Jobs, who was 56, had a legion of enthusiastic admirers in the high-tech world, as well as an enthusiastic and loyal following in the mainstream of people who loved their Apple-created devices and computers.
That admiration showed Wednesday in the expressions of surprise and sadness at Jobs' passing.
