Hello.

The community page is different than the hashtag.

When deepdives.blog is released you will need to put in for tags #deepdives

That will then post to the deepdives.blog and to hive blockchain

The community page will be less used as time goes on because there will be no reason to use it(dont earn tokens on community page). But you will if using #deepdives tag( when released in Jan 2022)
