Dear @luegenbaron
You're indeed very right that Steemit is not like Facebook and Twitter. Mostly: notification system on Steemit doesnt exist at all.
And for that reason I'm sending notifications to all people I know and every now and then I also send memos with notifications to group of new accounts. Those who do not reply and engage - I simply ignore in next "wave" of memos.
You may say that "I think spamming in general wont help you". But why would you say that? Without strategy I would probably struggle the way you do (and most people does on this platform). With zero to very little engagement.
But I guess I should not have to explain that to you.
Well. I really appreciate your time and I only can wish you good luck. As I wish everyone else who chose to struggle here. If you were right, then each of my post wouldn't have 100-200 comments. Unfortunatelly your assumptions are wrong and I can show you several other very succesful people here, who use memos for their benefits.
They all are doing very well.
Yours
Piotr
