For text, some of this stuff seems Apple/jobs-esque:
"When you post a job on GitHub Jobs, you're sending a message: you want developers who care about their craft."
I'm sure Jobs or Ive has said something like that in one of their videos.
"Starting next Tuesday, everyone will be able to search and browse jobs."
Sure, this is a standard type of sentence, but the composition is distinctly Apple- "when, who, what" - where the who is 'everyone' - no barrier to entry, straightforward, clear.
"Of course, .... if you don't find them useful. But we think you will."
that's again very Appleish. Confident of the opinion but not overly arrogant, suggestive of the outcome.
I'm not sure i can prove this with empirical evidence, but I definitely feel it.
You could also say that a lot of Acer's marketing has a Dell-like tone. But that doesn't mean Acer is taking cues from Dell.
One week is the added to the schedule to maintain the practice of releasing on Tuesdays. Tuesdays are the designated release day because they are good days for news coverage and the established day we synchronize our content with the mirrors that carry our releases.
