Hunting for someones blog

looking for someones blog in particular…

If I remember correctly there was a developer with Microsoft (probably a manager) who, I think used to work for Sun, produced a blog that was sometimes critical of microsoft. He became a bit of a legend cause he was producing this blog from inside microsoft and just when everyone thought microsoft was gonna wallop him they didn’t…they encourged him to keep going and to be honest.

After a few years he left microsoft and by then his blog was quite famous.

Anyone know which one I mean, really appreciate a link if you do?
