Ask HN: How much should i charge an hour, for private web development lessons

I'm a web developer, and been one for over 10 years, and recently i started writing about development, and i started getting a lot of requests to teach one on one lessons. I don't know much about this nor how much to charge per lesson, so i'm a bit lost. In my consulting and freelancing practice, i charge from $100-$300 an hour. So should i charge the same for the lessons?
