Ask HN: Why is everyone's marketing blurb so bad?

What is up with the amount of high profile projects who can't just say "We do X for Y"? Why does it always have to be some 'value' and 'impact' and 'delivering' and other ambiguous words to describe your thing?

Are these products a form of résumé wankery or is this actually trying to sell me something when I see this? Sometimes I WANT to use or WANT to buy something, only to become very skeptical when it comes to the marketing copy.

Also, contact-sales-for-pricing guy and login-to-demo guy, you're on the list too! I have a single break in the day to review your product, stop resisting.
