Thats exactly my approach too, I don't expect it to be around as long as big social networks like reddit, facebook or twitter.
So until this platform ends, I want to learn something, maybe even see how far I could get with my writing skills or the steems I may earn.. So also because I invested "0" it's kind of a game for me, to always try to reach a higher level. And along the way I improve my writing and language skills.
