It was only about 3-4 months ago and it was actually when searching for some good alt coins on coinmarketcap.com and steemit was in the top 20 with a large percent leap.
When I searched for it I ran into this site and at first only posted one blog post before snooping around and reading. I spend a good week reading and commenting on others and then created my first introduction post which made about $100 which floored me!
Since then I have been hooked to steemit and steem in general and love the community we have here. Huge amounts of support and I felt very welcomed from the beginning.
