I've had a few people offer to buy me a drink, and a random hash of some crypto currency really pushed people away and just putting a PayPal/Google link didn't offer that same feeling that something like this site would.
If you liked a talk, blog or some software I work on and feeling generous. I greatly appreciate it.
Though you are more than welcome to consume and read anything I do without a dime. Knowledge is power and I'm happy to share with you.
