Question: export with tags but hide "export" tag

[wry@mm.st]

Hi fellow org people,

I want to start publishing some of my notes on a website. My preferred
method is either org-export-dispatch or org-publish (maybe in the
future).

I have one giant notes file where I keep everything. Some people
prefer to have multiple files to compartmentalize, but I prefer to
keep everything together to simplify searching, organizing, capturing
etc. This is similar to the philosophy of dnote (a third-party,
non-org-mode note taking app at https://www.getdnote.com/): being able
to capture a note as quickly as possible is more important than
putting it in the correct place, and being able to search all notes is
more important than having them perfectly organized.

Towards the top of the file are more permanent entries, like my TODO
inbox, calendar, and daily checklist. Whenever I add a note, I
automatically stick it at the end of the file. When headlines are
completed or become more permanent, I sometimes refile them higher up
in the file ("percolate up", if you will).

Anyway, my preferred method of publishing would be to simply tag
headlines when they're ready to be included in HTML exports. Org-mode
includes this, of course, with the "org-export-select-tags"
option. However, I also want to include tags in the exported HTML, but
currently that means every exported headline will have the "export"
tag. Any ideas about how to export using this workflow without showing
the "export" tag?

Thanks,
Nick
