Letter to MP: one letter to MP, nothing to show for it.

Complain on blog: several letters to MPs of different districts, all of whom can now say that their constituents are writing to them and complaining about the same thing.

I don’t know the inner workings of Parliament but this is pretty basic for any remotely democratic government system. One person who cares a lot is less valuable than a lot of people who only care a little.
