Wot no blogging from work

I can only really do this from home now as my company either randomly chooses to block blogging sites or publishes a new HR policy saying we need to seek manager approval before writing (or submitting to) a blog. Even if you never mention anything about what you do, your company or your name. It irks all the more as they make this big deal about how work/life balance and right-on they are. Bobbins I say.
