I worked in a Senate office. Personal letters are taken seriously. It takes time and effort to write a personal letter. Petitions are too easy. If one hundred voters write separate letters about the same issue, it is noted. Of course, with the modern word processing systems, I will write a letter about foreign policy and receive a thank you letter. The politican thanks me for writing about Medicare and lets me know all his recent work in the field.
Well, jgnat is talking corporations and I'm talking politicians. Neither policy may work for JWs.
