Does blogging change the writing style?

Andrew Gelan argues:

I've been blogging for over six years, and it's affected my writing. More and more I write articles from beginning to end. It's worked for me to use Word rather than Latex. Somehow in Word, as in the blogging window, it's easy for me to just get started and write, whereas in Latex everything's just too structured. Really what's relevant here, though, is the style not the software.
