Say what you will about bots but they sure know how to make someone feel special. lol On a serious note though, I'd been wondering the same lately. There is one resteem service I use from time to time and I think I only saw a significant increase once. But to be fair I almost always at least break even with them.
Thanks for the insight and the informative article!
