It's both funny and interesting.  It raises the question of what makes
the two different -- why is one instantly recognizable and why does the
other trigger a gag reflex.  My thought is that bare excepts occur in a
context that makes their meaning clear:

    try:
        block()
    except SpecificException:
        se_handler()
    except:
        handle_everything_else()

The pattern of use is similar to a "default" in a switch-case construct.
Viewed out-of-context, one would ask "default WHAT".  Viewed after a
series of case statements, the meaning is vividly clear.
