It would be nice to see some invites, the weekend post are a great place for new users to meet some steady consistent users, some real people not automated bot welcome to hive messages, but real people.
I invited a new user over, they came they commented they got comments back, they met some people to engage with.
Yeah, as you point out it's not rocket science; Come along and engage and you will be engaged with...And your account will grow. Seems pretty straightforward to me. Thanks for inviting that user, I saw some good engagement from him and I hope it inspires him to stick around, and to engage in general around the blockchain.
