Someone else emailed me asking as well, I'm thinking I'll have to write a blog article on heading out here...
But yeah! Email sent. Short answer for those interested:
Internet access is... acceptable. I brought an Airport Express and upon arriving at the scuba resort here I just asked them if I could plug it in. They'd been hoping to setup wireless for a while but hadn't had a router, so they were fine with it. Voila, wireless. Problem being, it's usually 5-20kb/s, with my co-founder getting up to 200kb/s. I think it's because he has Wireless N to my Wireless B/G. Should have upgraded to a newer laptop before leaving, but live and learn.
Sure, hanging out and talking with friends at one of the beachside bars, going driving around the island and exploring, or reading/writing. I'm pretty easy to please when it comes to having fun, just give me a great conversation in a cool locale, whether that be a SF coffee shop, a BA tango club, or a Koh Tao beach, and I'm good to go.
Haven't been around, as of yet. Upon getting into Bangkok's airport I booked a domestic flight on over to Koh Samui and got there three hours after arriving in Bangkok. Koh Samui was a lot more touristy than Koh Tao, and in general just seemed to be developed too quickly. When I first got there I was amazed (beach! warm weather! jungle!), but in retrospect I prefer Koh Tao by leaps and bounds.
If anyone else has any questions, I'm not great about checking Hacker News comments, so feel free to hit me up by email as well, it's in my profile.
