What is a word for a person who loves to share knowledge? So far I have educator in mind. Is there any other word?

How about "Teacher"? –  Gaurav Sep 14 '10 at 5:48
    
@Gaurav: that could be an answer. –  delete Sep 14 '10 at 10:48
    
Shinto: yeah, but it seemed so obvious to me that I felt I must have misunderstood the question, and was hoping for clarifications. –  Gaurav Sep 15 '10 at 4:38
    
Guru, Professor, Master - all of them should fit well depending on the regional and circumstantial context. –  karthiks Sep 10 '11 at 15:10

How about "maven"? According to the Wikipedia article,

A maven (also mavin) is a trusted expert in a particular field, who seeks to pass knowledge on to others.

[Admittedly, many dictionaries define the word merely as something like "an expert", but the meaning is in flux, and the "person who loves to share knowledge" meaning is getting more common.]

Thanks @ShreevatsaR. Yah it is more closer to knowledge sharing. –  Thedal Sep 14 '10 at 8:59

Again, I must point out this was just a tentative answer; "maven" in most contexts just means "expert" or "self-styled expert" etc. — look up the dictionaries. –  ShreevatsaR Sep 14 '10 at 10:11

Although I don't have a good answer for the question, I don't think "maven" is understood by many English speakers. –  delete Sep 14 '10 at 10:48
    
@Shinto is right. And so is @ShreevatsaR. To my ears, maven has a mildly negative connotation which derives from the "self-styled" part. (Anyone can be a self-style expert.) –  Benjol Sep 16 '10 at 5:24
    
That describes me! :D –  user19341 Jan 4 '13 at 18:49

A professor is someone who professes his knowledge or faith, gratuitously, sometimes. To all who would listen.

A fountainhead is a person who is a source of all kinds of knowledge. S/he may not love sharing that knowledge, however.

On the other hand, why would a fountainhead deliberately dam up the works by refusing to share knowledge? Besides, isn't the job of a literal fountainhead benefit all the people who congregate around it? How could a fountainhead of knowledge not love benefitting others?

Yeah, fountainhead is a apt word to describe someone who loves sharing knowledge.

Within religion and technology people who are keen to spread ideas are know as evangelists.

"The Greek word εὐαγγέλιον originally meant a reward given to the messenger for good news".

For evangelists who are promoting knowledge of a certain type of technology or religion, spreading the 'word' is seen as it's own reward, rather than seeking any monetary reward.

How about "pundit"? A pundit is a person who knows a lot about a particular subject and who often talks about it in public

In addition to the excellent answers previously given with positive connotations, I offer this pejorative one:

pedant

...because loving to share your knowledge doesn't always mean others love to receive it.

That's not intended as a subtle dig at StackExchange users. I just really like the word.

A pedagogue likes to teach others things.

Pedagogue has a rather negative connotation, though. –  Chris Dec 9 '12 at 16:53

A few more words for people who share knowledge: teacher, "teaching assistant", tutor, mentor, coach, guru, contributor, author, polyglot, blogger, Wikipedian, ...
