Err.... but LinkedIn is just (effectively) a chat site, and a very low-traffic site at that. As long as I don't use my trading account password or my banking account password, what's the harm? For throw-away thing like FarceBeuk and LinkedIn I *do* use such crappy easy-to-remember throw-away passwords, whereas my financial accounts have regularly-changed horse battery staples. The thing that really annoys me is sites such as job vacancies sites that insist you use a bank-account-strength password just to frikking read the frikking job adverts.
