Yeah, time is an issue. I spend a lot of time on my writing and always wish for more time/energy.
Many of the Discord servers have a channel for promotions. Some of them have rules (like upvote one/two posts before posting your own) and others you can just drop the links.
One of the best services is Ginabot. She comes with a server as well. She sends you notifications of all sorts of Steem activities. She sometimes falls behind, but normally she's very good. Here is an invite to that one. Hopefully, someone can help you set it up - I can't remember how it was done, lol.
My discord, btw is viking-ventures #2883
Thank you for the tips! This Ginabot seems really helpful, I'll have to get acquainted with it this weekend! :)
