Thanks for this post. I have used a bot a few times and did check the voting power of it before sending SBD but still couldn't see the benefit but I didn't have much to send so that may have been it. Everytime I get SBD I convert and power up and then think oh yeah I should keep some side for a bot on a great post with little love.
I'm not a fan of them posting in the comments section either but I guess that's their way of self promotion.
I'll check out the bot page too. Looks like it will be very helpful if choosing to use a bot.
Awe yes. The more SBD or STEEM a user sends the bigger the spread will be. But with that comes more effort in making sure you are not over bidding.
