Why should it matter anyway?
Are you asking why staying on topic should matter,
@Axel Slingerland ? I can give you my answer, at least why it matters to me; but it also makes a difference for the SEO for the forum, because there is a dedicated thread about a specific topic that people might search for online and find the answer in our forum.
However, the reason I like it is because i often want to find something that someone has suggested or recommended, or just mentioned at some point in time in the past.
So, I enter that word as a search and look for the thread where we talked about the topic I am interested in, and then I can read about it, or watch the video again, and find it easily if the whole thread is on topic.
Also, it make much more sense to someone who is just reading through the thread. A good example is when
@Beth Gallagher started a thread about members we remember from our first SOC forum, called “Gone, But Not Forgotten”.
Somehow, the whole thread got WAY, WAY off topic and is now about jumping beans, for Pete’s sake ………. How did that happen ?
Now, Ken has to go in and moderate that thread, and move the off-topic posts somewhere else so we can have the memorial thread back again.
It matters…….
