1. Since the last post BY @JorgeStolfi some six hours and four pages ago, there may have been 30 posts ABOUT @JorgeStolfi. I am flattered and moved. Sorry @fonzie, but as the poet wrote
Cesse tudo o que a antiga Musa canta
Que outro valor mais alto se alevanta

2. Thanks again for the offer, but I would rather not have any bitcoins, and I do not intend to help distributing bitcoins to anyone, my students or not. I am sure you will find charities or other worthy projects that will make much better use of the money.
3. I got to 65k tweets before knowing about bitcoin; mostly on politics, a bit of thechnology, humor, etc. I was looking forward to commemorate my 65535th tweet, but then Twitter switched to the approximate "65K" count format. Darn. But I was bored of politics anyway and decided to take a long twitter vacation. By the way, it was through Twitter (specifically @falkvinge's tweets) that I first learned of bitcoin. Since December I have been mostly wasting the stolen taxpayer's money here instead, using twitter only once in a while to warn people about bitcoin.
4. Why do people assume that I "still do not understand" bitcoin? In my view, it is the shrillest bitcoin enthusiasts who do not understand much about it and how the world works. Like those who still claim that bitcoin will let people evade taxes and buy illegal things, or that bitcoin is a safer investment than plain cash, or that China is irrelevant, or that the volume in the blockchain shows that people are
using bitcoin --- or that the right technology, by itself, can save people from corrupt politicians and greedy bankers.
