Personally I don't think that a release announcement needs to be "marketing heavy" in the first place.

That's really the heart of the problem - in an effort to sound exciting, many parts of the article are just wasting the reader's time rather than simply explaining how things work clearly and directly.

No release announcement has the time to explain how things work. I actually think in hindsight what Rich did by including a video in the Runes announcement worked well. I will have a livestream tomorrow.
