Apple can take pride in having the most hardcore fans in the tech world. In fact, according to today’s General Sentiment report Apple topped the list for the fourth quarter, expanding its lead over rivals Google and Microsoft. Apple geeks are more passionate than the Twilight moms and Harry Potter fans put together, but who do they pay attention to on Twitter?

We partnered with PeerIndex, to come up with a list featuring the 25 most influential people tweeting about Apple. Our top 25 list is not ranked based on their overall PeerIndex score , but based on each one’s topic resonance score, which measures how their actions within the Apple community.
