I can not provide my opinion on stand alone startup blogs, hardly you will find any stand alone startup blog with a good ranking. I may be wrong. Startup blogs has a different nature, you listen and read very financial terms, stories and relations. You will funding, venture capitalists.
I am sure how should be a startup blog, in nature and ranking and content. I also do not for whom are startup sites or blogs. But one thing is sure one should have interest in it as I read social media and tech news.
As I have listened starting and running a startup blog is not child’s play.
