I don't like scrolling to get to the main point. Doesn't journalism follow the inverse pyramid paradigm where each sentence is less important than the last? If so, one would expect PR releases to follow a similar idea.
Yes, succinct and concrete headlines are important. "Not burying the lead". But my criticism is a lack of specific "How it works" copy on most product websites.
The problem is often one of having to lead the customer through a sales process. For eg
1) I want a reliable product... like BRCK .. okay.
2) This product really meets that criteria. Prove it.
3) So, is it useful?
4) Fine. Because of 1..3 I want more detail and to buy one.
For instance with http://gridspy.com (my site)
1) So, why should I monitor (energy usage) at all?
2) Okay, so why GridSpy (not a competitor)...
3) Fine, tell me more about what you do...
4) Lets get started. Give me a quote on some hardware.
It's a process. You can't just lead with (4) because the customer hasn't yet decided that they want your class of product at all.
The problem is not communicating what your users care about. Thats such a big part of UX, looking at it from a new customers perspective, instead of your own.
