Not really
It isnt “your thread” You don’t own it, you didnt pay for it . You start a topic that interests you, if people like it they comment if not they don’t. Sometimes, as is the nature of human conversation, topics shift usually m’iniyan linyan be’oso inyan, but sometimes over time it changes and moves more from the original to a new inyan . You can try to bring it back and if people like your comment they will reply. But I don’t think people are required to reply only within the narrow confines of the orignal OP.
