Is it only for photography nerds at the moment or everyone ?

EDIT :Just want to get my friends to try anything ftom the frediverse and i think pixelfed is the only platform that ordinary people will want to use in the frediverse i aslo want to try it but atm they are not taking temp mails and every instance seems to need a real one which i am not comfortable sharing .

EDIT : Also is there any way i can browse it for some time without making an acc ?
