I've seen various articles on the web in the past expressing the opinion that placing swear words in comments should not be a reflection of the programmers profesionalism.
I haven't seen these sort of articles released recently, though have on occasion heard opinions stressed that its ok.
As a general case, I'm of the opinion that as a programmer you are responsible for quality of the entirity of your conribution, which you perform in exchange for your salary.
What the customer/employer decides to do with that code, unless expressed otherwise in the contract is totaly their business - not that of the employees.
Therefore, should the business decide to release the source code for the product, the comments become as public as the user interface.
This leads me to suspect that if I am right in suspecting that "cussing in comments" is passe, the commercialisation of open source could be a contributory factor - or perhaps its just a reflection of the maturity of the industry?
Or maybe I'm wrong, and there is still a belief that delivery of code is limtied to user experience.
Either way I'd be interested in the prevailing attitude towards what people percieve is a professional attide to software development. I'd also be interested if people have the same attitude to code released personally to that developed under contract?
