I once emailed Woz about some trivial question about the old Apple machines. He emailed me right back with an apology about how he was too busy to answer all these kinds of emails and then in the next sentence, answered my question anyway.
Different story. I once asked a question to the author of 7-Zip to include it in a software and received in return a link to the FAQ!
And even when Woz isn't responsive himself, it seems he makes sure his emails get answered. I emailed him once a few years ago -- I forget about what -- and his wife replied with a kind, detailed note.
