[II2II]

I suspect the use of profanity was to grab people's attention, rather than for shock value. I would consider it as unprofessional, much as I would consider an article titled "Stars that go boom" to be unprofessional. I would suggest that it should be discouraged, mostly because we don't want scientific journals to come off sounding like tabloids. Yet I don't think that it automatically results in degraded discourse.
