Here are some suggestions for segregating and denominating users:
1. cool kids versus rejects
2. freshmen, sophomores, jrs., srs.
3. we could try a caste system; total newbies could be the untouchables
4. geeks versus freaks
5. those of pure blood versus the rest of us mongrels
6. those who truly want to make america great again versus those who only want to get high
7. photos versus autos
8. sativa versus indica
9. master race of hydro growers versus lowly soil growers
10. as Orwell said, we are all equal but some of us are more equal than others
