Okay, I won't say I haven't got other hubcrushes but my very first hubcrush was on Mrvoodoo. I can't help myself, I adore his writer's "voice" and so, even if I don't comment, I eagerly await his next hub, and I read them more than once.
Now, not to insult any of the others I have or have had a hubcrush on, Mrvoodoo is probably one of the few who would not treat me differently even if he knew, which is why people don't disclose their crushes openly. They are afraid the object of their crush will treat them differently, and that would just ruin the whole thing, wouldn't it.
