Where to start with churning.
People ask me where to start with churning, and my honest answer is a little boring: pick one of these sites, start reading, and Google anything that doesn't make sense. That last part is the whole trick. The vocabulary looks like alphabet soup at first (MS, DPs, SUBs, 5/24), but every one of these blogs explains it somewhere, and a quick search fills the gaps fast. You don't need to understand everything before you start, but you need to start, and let the reading catch up.
Here's where I'd send someone.
Miles to Memories is the gentlest on-ramp. It covers the fundamentals of award travel alongside the current offers, and if you'd rather listen than read, the podcast and YouTube shows walk through the same ground. Good first stop.
Frequent Miler is the deep reference. Thorough guides, side-by-side tables of the best current offers, and a weekly podcast that recaps what actually mattered. When a deal confuses you, the full explanation usually lives here.
Danny the Deal Guru is where the easy wins live: daily deals, bank account bonuses, and gift card promotions, the small stuff that adds up while you're still finding your feet. Low stakes and quick to skim.
Miles Earn and Burn is the daily signal once you're rolling. Short weekday posts on time-sensitive plays, leaning toward manufactured spending and the more advanced stuff. It moves fast, so come back to it after the basics click.
Once those click, a few more worth following: The Daily Churn if you like a podcast in your feed, plus Churning Life and The Credit Chronicles.
Start with one, not all of them. Read for a week before you apply for anything, and keep a note of every term you had to look up. In a month the alphabet soup reads like plain English.
