I believe the answer is:

wittgenstein

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

'genius it's been said philosophically' is the definition.
I can't judge whether this defines the answer.

'isn't tweeting? wrong' is the wordplay.
'wrong' is an anagram indicator.
'isnt'+'tweeting'='isnttweeting'
'isnttweeting' is an anagram of 'WITTGENSTEIN'.

Can you help me to learn more?

(Other definitions for wittgenstein that I've seen before include "Ludwig --, Austrian-born philosopher" , "British philosopher" .)

I've seen this clue in The Guardian.
