When one of your favorite bloggers (not necessarily BZP bloggers, just bloggers in general) posts a video in which they speak and you hear their voice for the first time.
Their voice never matches the voice I read their blogs in. Never, ever, ever.
I mean, it's just bizarre how sometimes bloggers (and writers in general, honestly) can have these passionate, powerful writing voices that force you to think deeply the issues they blog about, yet when you hear their verbal voices, you'd never expect that they are the same person who wrote that great blog post you come back to again and again. In fact--and this is probably just me because I'm paranoid--your first reaction to hearing them speak is usually something like, "No. You're not my favorite blogger. You're too different from what I imagined the blogger would sound like in real life. You're someone else."
It's like seeing your favorite voice actor's face for the first time. If you're anything like me, it is almost always a surreal experience to hear a voice you know and love well coming from the mouth of a real human being. Granted, you do get used to it eventually, but the initial experience always takes me off-guard.
Maybe it's just me, but it's happened to me with three of my favorite bloggers so far and each experience has been almost exactly like how I described it above.
