Lol, love it -- "You better reply to my comment."
As for your question, I put my SBD into SP almost always other than a few donations I've sent since I've been on the site.
I have no idea how much work we have to put in, honestly. I do my best here everyday commenting and I post something at least once a week that will hopefully get someone's attention. Thankfully, you read this post and decided to add your thoughts, and I thank you for doing so. Let's see - I have been looking at some of the larger accounts and they seem to be ranging in the thousands of posts, maybe that's what it takes? Mind you, I wouldn't suggest spamming at all, just keep commenting and posting what you deem good content to the platform. I think conversations would add up eventually, open dialogue should count for something, it shows that you're interested in the community itself, and what other people have to offer.
You're a lot further along than myself, I am going to try and keep going and doing what you've suggested. Let's help each other out as much as possible.
By all means, keep going!
