I am not that far behind you in days since I first signed up on steemit, but I definitely feel you know more than me. lol
coffeesource.net is new to me. So is smartsteem. minnowbooster is too crowded right now so might try out smartsteem. thanks and congrats on the success.
It's a real pain to get a minnowbooster upvote. They have even put a bunch of limits and it still isn't working. So far smartsteem has been giving me good results. I'm very satisfied with the service for the time being. Hope it won't get crowded too soon.
