🎂 3 year anniversary 🎂
Just to repeat the advertisement immediately above: you can buy the limited edition NFT for 0.11 Eth which will unlock the annotated edition.

I own 100% Week In Ethereum. Editorial control has always been me.
If you’re wondering “why didn’t my post make it into Week in Ethereum,” then here’s a hint: don’t email me. Do put it on Reddit. It’s amazing to me how many people email me when every issue has a link at the bottom saying not to email me to get in the newsletter.
If you’re unhappy with editorial decisions or anything that I have written in this issue, feel free to tweet at me.
This headline stays as long as so many people continue to link to old URL and not the right one: weekinethereumnews.com
