This all the way :3c that's because that's what's the answer I'd prefer to be given.
I love making guesses and all that jazz in the comments, they're fun to make and fun to read for the creator. Being met with silence is kinda disheartening sometimes (unless it's a super big comic and the author can't answer all the comments / you know the author doesn't usually answer to comments because they just prefer it that way), when an author answers me with something like "we'll see!" Or whatever I feel like it's kind of like a small highfive amongst the two of us, if that makes any sense. That way I know the author is cool with people theorising in the comments as well c:
As a creator I do the same :3c I don't answer, but I appreciate the fact that they take their time to comment and guess.
