Wonderful and indeed a very informative Article dear @gtg. You shared about #steem-pressure which is meant that how much space is being used and in future while growing steemit which challenges will have to face us. This specification which you didn't recommended is very costly for a common man:
For now, for a low memory node, I would say these are: x86 CPU, 24GB RAM, 100 GB SSD. And I bet this will not work after 1st quarter of 2018.
Anyways, I have one question @gtg... It might be a stupid one but it came in my mind so I am asking?
Withe passage of time will a user need a high specs system to run steemit accurately or Not....?
From my side this blog post is one of best post in connection with great information on technicalities of steemit(Hidden Things). I'm so blessed that you're connected with me here. Keep your great work up and all the best!
