I'm a little stuck... Click here to teach me more about this clue!

'tech bro hub?' is the definition.
I can't judge whether this defines the answer.

'friend circles seen around key' is the wordplay.
'friend' becomes 'pal' (pal can mean a friend).
'circles' becomes 'oo' (resembles two O's).
'seen around' is an insertion indicator.
'key' becomes 'alt' (the Alt keyboard button).
'oo' placed around 'alt' is 'oalto'.
'pal'+'oalto'='PALO ALTO'

Can you help me to learn more?
