No, but I live in Berkeley and if you want to experience mdakin face-to-face over-a-beer drop an email to the obvious username at alum dot mit dot edu. I attended the first Startup School in Cambridge and had fun but I'm not really totally in startup mode right now which is why I didn't apply this time around.
I think less with the F key is a bit better, as you can stop it and scroll back through potentially long ruby stack traces (especially when you're doing it after the fact), as well as search and jump around in the file.
