I really enjoy the newsletter format permies uses. I think I was subscribed around #10,000...Memory check!?!
It's like having a guide, instead of trying to tackle the mountain on your own.
I have a few questions:
What was the born-on-date of the daily-ish?
What did the format look like in the early days and how has it changed? (Maybe you could pull one from the archives)
When did it experience the most growth, was there a tipping point?
Some other random figures would be cool; click-through rates, total links posted, etc.
Thank you and keep on keepin' on!
