Thank you for the interesting discussion,

what and why do you write in G2k?

May I start with why :)

Honestly, I start writing in G2K to feed my own Ego.
Looking back my blogs have had contents I hope people read then they say 'WOW'.
Anyway, I gradually learnt what John Maxwell said,
"They don't care how much you know untill they know how much you care (them)".
Nowaday, I still be 'individualistic' person. However, I also feel easier to get along with people.

What I write.
There are three criterias of what I love blog it.
1. Less judgement 
2. More questions (as yours) 
3. High hope 

In conclusion, I blog Gotoknow with personal believe that 'developing oneself lead to developing society'
