Just to say it out loud: there are plenty of geeks w/o a VPS, either because they hack on things that don't generally need a server (like hardware, or radio, or any number of other geek pursuits) or because they've historically used local gear for their compute tasks.

If you have a VPS, I agree, adding a cronjob to it is both cheap and easy. But it's silly to assume that anybody who is a geek has a VPS already.
