đź‘‹ Before you go
I've got a big favor to ask - keeping Blaze running isn't expensive, but it does all add up, so I'm asking readers like you to help, if you can.
That's why I'm launching a Patreon page!. Nothing flashy, just a way for folks who find value in these newsletters to chip in a little each month. In return, you'll get:
- Real say in how Blaze evolves — vote on new topics, features, topic curation ideas
- First dibs on merch (details still cooking)
- That warm fuzzy feeling knowing you're supporting something that saves you time and keeps you plugged into great tech writing
If you are getting value from blaze, checking this out would mean the world. And if you can't contribute, no worries—the newsletters keep coming either way, and you can follow along on patreon for free.
Thanks for reading and being part of this nerdy corner of the internet. All the best - Alastair.
