Well, I rather prefer to break PEP8 in this case (See http://stackoverflow.com/questions/10739843/how-should-i-format-a-long-url-in-a-python-comment-and-still-be-pep8-compliant?rq=1). I don't trust online services as we cannot rely on them and I tend to think we are building stuffs for the next couple decades. Moreover, we can also argue about user privacy.
