I'm not on twitter so maybe there is something I'm missing, but is there really no better way to do this than posting /images/ of updates? It seems like a tweet embedding service would be really easy to write.
There are plenty of better ways; Giles just feels like doing it that way. Maybe you also noticed that the post includes pictures of Lady Gaga and Britney Spears that don't really contribute to his argument...
Please, when you post screenshots do not use JPEG. It makes everyone's eyes hurt.
