Following?

Te
Can someone explain the benefits of "following" someone. I go and follow certain people because I am interested in their posts, I hope they get pregnant soon, and I want to be alerted when they do post that they are pregnant! I want to be a support team for them and cheer them on.  But nothing. No alerts. Glow won't tell me when they posted something or their progress. What's the point of following? 😕
