Why pay for the service of installing the steempress plugin when I can do it for free?
Owwh..... you mean what kind of Wordpress plan and hosting plan is needed is it?
Based on my experience, I got a business plan from Bluehost for 3 years (full Wordpress feature, unlimited domain hosting option etc..) and installed steempress on my personal website. Check it out, it's https://kristiankho.com
I can't say for free wordpress.com blog page since i never used it but I understood that the functionalities are very limited.
If you want have a blogging website, you might as well own it. And also not do it just because you want the Steempress upvotes.
You can however, try services like xopus, timeets or vornix. it's not an endorsement since i personally feel that it defeats the purpose of steempress.
