Hi dear Welcome back first about your first interest of "Posts about topics I enjoy - music, books, technology, cryptocurrency, Steem" I would suggest you to join @jerrybanfield if you have not followed him yet, but I don't think so, because he is most popular steemian I have seen yet but I think currently he has all interest you need now to follow, and in second he has many others interested projects you may follow them in future if you want.

Cheers,
