Absolutely agree Jelena - and that's been another of those Marilyn Pratt or equivalent tasks to go and have a chat... unfortunately they don't always want to hear it.
Often because the people writing such pieces are doing it second or third hand ... and the better option is to get someone who knows what they are talking about to expand on it.
Btw I don't tend to see them in my spaces fortunately because our folk have all been educated on what's expected and most of them are regularly involved in SCN. 
What I have done in the past is put some internal pressure on people to post the sort of content we need - but IMO that really needs to come from SAP employees who are regulars in that SCN space and can advocate internally for better quality content.
As a customer or partner if you feel strongly about a piece in your space ATM I would suggest 
a) commenting on the blog as to what content you would need to make this useful b) looking at the leaderboard for any SAP employees on the list and DM them about getting some better content. Silence is often taken tacit consent to these sorts of blogs unfortunately.
Best I can suggest for now ... SAP is a big company... getting the message through to everyone is always a challenge.
