For me even the Steemvoter auto-voting is about identifying a promising new author with a lower reputation and committing to supporting them with auto-votes.
If you're good at doing that then you will be rewarded and you will help the new author to get the exposure.
I'm not a huge fan of encouraging self-voting, but even so, you have to invest in some SP before that will work and a new author getting 0.01 on their first 5-10 posts is unlikely to invest.
It's a real shame that steemsql has gone to an expensive subscription model because I was considering doing some analytics to back my theories up about not just retention but also the unsustainability of the SBD price pump. Cest la vie.
I use Steemvoter for partly this purpose, and to support peers around the same level.
The 2nd account is for SP curation rewards.
SteemSQL is a bargain for me, I use it on a least two posts a week - one of those has just paid out the monthly subscription for the next four months 😁
I can see that for an established Data Analyst posting regularly like yourself it's probably not a big deal. But for someone doing a few ad-hocs and experimentation with no established data analysis interest amongst their following I think $70 US a month (up from $0) is a stretch, so it's a barrier to entry. Each to their own though, I will just focus on something else and maybe have another look when the SBD price comes down.
Fair enough.
I don't look at the cost in USD. If the price of SBDs come down to $1, I'd still make 3/4 times the monthly cost with a post.
More engaging posts like this one and you wont need to worry.
You could also hire a data analyst to do the work I guess? :)
