>if the condescending tone of the top comment is ignored it becomes valuable feedback. good libraries/api's (free or otherwise) do not need to use marketing buzzwords to sell themselves when a clear demonstration of the functionality is usually more than enough.
this fallacy is called affirming the consequent. yes good libraries might not need marketing but that does not say anything about whether good libraries can have marketing.
its anyone's best guess whether apis/libraries with documentation that have buzzword-y marketing get more usage than those that entirely market themselves based on functionality.
Think of buzzwords as familiar faces for the readers. Sure, you can overdo it and make a buzzword soup, but a few buzzword can give the reader a quick idea of the product.
