Internet Explorer - IE is the slow kid. He eventually grasps concepts and is very proud of himself when he does. However, most people just shun him because while yes, it's great that he can count to 10 now, he's 18.
Firefox - Firefox is the "MacGyver" kid. He has a ton of neat and cool gadgets and he's generally very reliable, but even he can get in over his head sometimes.
Google Chrome - Chrome is the really smart kid who gets A++++++'s in everything. He doesn't have any fancy gadgets or any real personality, but he's reliable, intelligent, and efficient.
Apple Safari - Safari is the spoiled brat. He thinks he's cool and all that but there's really nothing separating him from everyone else performance-wise. Since he was raised amongst rich, spoiled people, he works quite well in their company. However, when grouped with "poorer" folk, he tends to be quite useless.
Opera - Opera is the average kid. He has his share of good and bad moments.
Lunascape - Lunascape is the kid whose parents force him into twenty-billion different hobbies. Sure, he's eclectic and has the skills for many a situation, but because he's so overloaded, those skills don't really shine through at all.
Netscape Navigator - Navigator is the kid with parents who still live in 1995. He was raised to believe CRT TVs with rabbit ears are "cutting edge" and that 24kbps dial-up is "blazing fast". Sure, at one time his family *was* on the cutting edge with technology, but now they're just stubbornly clinging on to a decade long past.
AOL browser - AOL is the kid whose parents controlled and micromanaged his life. If his parents didn't absolutely agree with something, they made sure he never knew about it. The only way his life could be any further controlled would be to put him in a plastic bubble. AOL should not be confused with AOL Explorer.
AOL Explorer - AOLE is the kid who desperately tries to fit in and be cool but he's always several steps behind on the latest fads and trends.
Of course, this is purely my opinion so obviously I'm wrong
