I wouldn't assume it has anything to do with the content in most cases, specially with how easy it is for a post to go unnoticed on Steemit. Could just be the right people were not online at that moment, or tons of ppl posted at the same time. Keep doing your best and when someone spots your news post and go to look at your page, the will see you have been making great posts in the past, and that will likely get them to follow you.
