To add to this, from the @U2 fansite About/FAQs:
"This site is not produced by, nor affiliated with, any or all members of U2 and/or its management. This site is produced by U2 fans for U2 fans"
Is this your main job? Do you run this site for a living?
No. Everyone on staff "works" for @U2 as a volunteer/hobbyist.
