everytime I see a project using google groups, i think it is already dead. Gladly yours seems to be used quite often. At least you can search it even years later, compared to an irc or slack channel.
Other day I thought about contributing to Yarn, the Javascript package manager, but the only way that I found to communicate with the developers were issues in GitHub. Since I didn't know if the feature I wanted would be well received, I just quit.
i'm not the parent, but that is the main reason i try to abstain from posting on public forums unless its under a pseudonym, which my github account isn't.
I'm not trying to say that my anonymity is guaranteed with irc, its just unlikely that future employers and similar link it to me.
Requiring everyone to sign in with full, verified name limits what people can talk about.
In fact I'd almost recommend against commenting online on anything using your full name.
