Hello franco / @yungpeng, I work with a a couple of groups that try to help new users out on steemit, The first group is @newbieresteemday, and here is their Discord Chat room. The second group is @greetersguild, and this is their Discord Chat room.The goals of both groups overlap and both work pretty close with each other. Like myself there are several of us that float between both groups.
I notice right off that you only used the one tag, you should try to use all five as that will give your post more visibility, keeping in mind that the first post you use can not be edited or changed. @teamaustralia is another community you may want to look into, and they use the tag #teamaustralia. #cryptocurrency, #blockchain, or even #newbieresteemday. Here is the list of tags that are widely used.
One last thing before I go, @greetersguild is have a contest for all new users and any one under a 45REP, Here is the link to it. The post is a little bit long, but that is because it is three contest in one. All of which are easy to participate in just drop you link say who sent you if you want, and make a comment. It will be running for 7 days, (til post pay-out), and you can add a link every day increasing your chances of a win.
If you have any questions feel free to ask them here or DM me in a chat room, or ask on any of my post. Enjoy your stay here, and the only "publishers" I know is @rohndak she runs the fiction writers workshop, and I think at one time she was talking about developing a publishing type company, but I am not real sure about that.
