Sometimes choosing tags may seem arbitrary. I used to always include the neoxian tag for no particular reason but nowadays I usually neglect it unless I can't think of any other relevant tags.
One tag I almost always include is proof of brain because it is a general, all purpose tag but also because, well, I'm using my brain (not AI) to intelligent make creative posts.
The other most common tag I use is gardenjournal for easily visibility within the hivegarden community. Every month, we hold a challenge.
I also use miscellaneous gaming tags to increase visibility of my posts within the different gaming communities like hivegaming, oneup, etc.

All second layer tokens get powered up of course!
