I didn't know about steemexchanger until @danielsaori featured this post so i cannot talk about it. But it sounds like its been a blessing to steemians so kudos
That been said. I am a huge fan of "do it yourself" and i am quite good at figuring how stuff work. And in the small steemibadan group im part of ive been able to put a lot of people through some functionalities. Its not much but it helps them get bearing. I do not think we need a reason to be good to people here. It should be unconditional. Ive gained alot from steemit especially from the people ive met and they did so without reservations so i always try to help as best i can
Absolutely, helping others will always have a positive spillover effect on our lives want those who are to come.
