I started the node thread to see if any new members are serious about Bitcoin. I installed core when I was still a newbie. Mind you, if I had to rely on public WiFi exclusively today. I would be a Hero member by the time I had synchronised the current blockchain.
I don't think there is any harm in doing what you are doing, but, in my experience, most of the replies are likely going to be offtopic. I tried once, and the 99% of the replies were from users that didn't even bother reading the rules I clearly stipulated. Nevertheless, I did obtain a couple of nice replies.
When I did this, to be honest, I just feel it was pointless, and got angry anytime I saw they didn't even read the rules. But maybe you have enough patience!!
Maybe you can just advice that if someone don't read the rules of the thread, they will be directly into your ignored list
EDIT. I actually had an idea... Why don't you create a post about the forum policies? I mean a kind of exam for newbies, in where they need to ask some True/false (maybe) answers to your questions or statements related to the rules in here. Maybe, by doing so, you can encourage them to go and read the rules for once
