hey @patrice I was looking for info regarding @smartsteem, I started to use it, I like it although I have always thought if is ethical or not to invest or send your sbd for upvotes from people. When I started on steemit (not to long ago) one of the first things I did was to read this: The Complete Steemit Etiquette Guide (Revision 2.0) which was very helpful, later I concluded that most of the people dont check the FAQ page.

Anyways, I bump into this post for the challenge, but I see most of the conversation has nothing to do with it, still very interesting!

Keep up the good work! =)
Oh! and btw... I totally agree, self up-voting multiple times your comments is kind of selfish!
