I've met some similar situations on a gaming forum where some people were active just for a while and when they needed help they were already forgotten, while at the opposite pole there was a man who showed his support and activity until that article written in his memory came out. It's sad but it's the cruel reality and no one knows what the next day will bring him but it's his job to maintain the connections in a place where people got used to see posts and updates from him/her.
In the end it doesn't matter how well you write those articles because you get cool rewards and new followers who make you famous and the minimum you can do to show your appreciation is to take a few seconds to write more than just a thank you while the people who left the comments definitely spent more time reading and then sharing their thoughts. It's about the respect that should be shown from both sides.
