could blogging make us happy?  

huumm, i'm happy if my blog gets many responses from others.
yes, of course you can make friends through blog, and money??.. it depends on what kind of blog you have i think ^_^

for some people blog is just like a diary where they talk about themself, their thinking, experiences, etc.
by just sharing it to others can make them happy.

Moreless... it gets boring

in most ways.. my blog is my outlet.. i write everything i want to write.. personal happenings, points of view about a certain topic, etc.. -- i write it all there.. im more into written than oral so i guess i can really express my view through writing.. well, bonus part of blogging is of course, earning.. that's what actually made blogging more interesting.. hehehe.. if you have time, you can visit my simple, nonsense blog.. http://leizlmarie.blogspot.com ..thank you..
