This is not the case with all communities... just ours, as we are technically a "closed" community. Applicants are assessed before being allowed in. The reason for this is that we pride ourselves on quality content and true Steem dedication. We are a very proactive community and those that do join us on discord, make a commitment to get stuck in... so whilst we "gather" there - ALL the action does in fact take place here... much like this initiative and many others that we have been behind.

Discord is simply a space which allows us to convene in a "live" manner, as there is nothing like that here.

Hope that clears it up a little.
