With more than 10 years of experience in Information Technology, I have come to realize few things:
1) We are humans. We work with other humans (at least until robots take over our jobs). We build software for humans, so it always makes sense to be nice to others, coz' end of it all, its all a very "human" world, so its nice to try and be humane.
2) Knowledge is of no use unless we put it to use, discuss with others, debate, and collaborate.
3) Its important to pick up interest in things outside your "regular" work, and possibly beyond Social Networks too!
