The great thing about knowledge is that sharing it with others isn't a zero sum game. Unlike sharing a bag of sweets (candy for those of you across the pond) where the more you give away, the less you have yourself. Give away your knowledge and you've still got it yourself.
So do please keep sharing - here or anywhere.
Didactic (from Goggle):
"When people are
didactic, they're teaching or instructing. This word is often used negatively for when someone is acting too much like a teacher.
Didacticism is a philosophy that emphasizes instructional and informative qualities in literature and other types of art. The term has its origin in the Ancient Greek word διδακτικός (didaktikos), "related to education and teaching", and signified learning in a fascinating and intriguing manner."
So I'd ignore the negative connotations Step, and focus on teaching others in a fascinating and intriguing manner
