The Hive is a collective on Interference that "assists" other members in determining how to think about U2 and their music.
For example, upon coming to Interference, you may have thought that 80's U2 was superior to 90's U2; or you agree with the band that Pop was a mistake; or perhaps you foolishly thought "One" was a good song, maybe even better than LWTSH; you may have believed that somewhere, sometime, a song was recorded by someone that is better than "Acrobat"; perhaps you believe the band, their record label and their representatives when they say the reissue of Achtung Baby was not remastered; maybe you judged U2's music on its merits using your own individual taste, and not on how obscure it is and whether it was pulled out of mothballs for the most recent tour; or perhaps you have other things to do in your life other than to hang out in the Random Music Threads, jacking up your post count.
If you naively believed any of these "incorrect" thoughts, The Hive will help educate you.
The most important part of Hive membership, however, is to vehemently insist that your opinions are your own and that you're not influenced by others. You may even deny sharing any opinions with other Hive members. The stronger you do this, the more likely it is you're a member. Oh, and you have to take comments about The Hive way, way too seriously. If it's easy to get you worked up, you're probably a member.
Stay here long enough, and eventually you'll be assimilated. Otherwise, you're free to make up your own mind. While you have one.
