Tell me more about this!

German law forces you to provide address/contact info on any commercial website (just running ads qualifies).

But this is often "abused" by lawyers to basically send cease-and-desist letters to small websites that don't have one (typically because they're unaware of the law, not because of malicious intent).

		On any website, except one that can be proven to have absolutely no commercial utility whatsoever. Your blog qualifies as commercial if you write about software at all, because someone might see your software posts and use it to influence a hiring decision.
