I think those who do best are those who mindfully engage with others across the communities leaving meaningful comments and get to know people that way.
I agree with this.
But the hard part for some newbies is to learn to be patient and not get frustrated dealing with resource credits when starting. Because is a paradox that engagement is indeed the key to success, but in Hive when you start the scarcity of RC doesn't allow you to comment much. However, in the end, it's all part of the learning process.
