The main thing that comes to mind when I look at his work is
the simplicity of it all. The jokes are the most important thing to the comic,
and there are no superfluous details that could get in the way of the jokes
being told. Backgrounds are either non-existent or only consist of one or two
objects, with no use of perspective, all the characters are of the same basic
design (with only accessories to tell them apart) and the comic has a purely
black and white colour palette... Even the narratives tend to be simple, often
consisting of a list with a different joke in every panel instead.
The comic is also updated very frequently: a new 4 panel strip is posted every weekday, so
the simplicity helps in this department. Huber needs to crank out a comic strip
five times a week, so he can’t spend his time finely illustrating every little
detail.
What this says to me is that the joke is the most important
part of the comic. Nothing must get in its way, be it overly complex
backgrounds or wordy dialogue or even time (or rather the lack of it)
