And there is a difference between boycotting evil companies such as Nestlé and shutting off your weblog for a day. Firstly, the former hurts the wrongdoers' profit margins directly (by a small amount, granted, though if enough people do it it adds up), whereas all the latter does is annoy people who are not Part Of The Problem (except in the most dogmatic Marxist/Maoist interpretation). And secondly, by buying Nestlé products, one is actively funding genocidal profiteers; by keeping one's weblog going on December 1, one is not causing any more AIDS deaths nor detracting from funding.
Has my lefty-cred(TM) gone out the window now? Guess what; I don't give a tuppenny stuff.
