Care to share?
We encourage our developers to keep personal blogs and talk about technical problems they've encountered at work that are not core competency or core IP. We've been doing it "don't ask don't tell" style, but it's time to write something down.
Update: thank you all for your answers, we've implemented a policy for this last week - the full text is here.
