PoketyPoke is a new service that calls you when you have a conference call and connects you automatically. Why it took someone that long to think of and implement this is beyond me. This is like GTD times 80 bazillion. If implemented correctly, you’d never have to remember a conference call again (which could be a problem, I suppose if you’re supposed to give a presentation or something).

If you were me, you’d never have to worry about the timing of your meeting reminders (although I’ve got a pretty effective system down at this point).

I suppose the only downside is that is probably won’t be able to use Skype to call in for free. But, I think you can get a SkypeIn number for somewhere around $5 per month, so if that’s less than you’re paying for your normal phone or mobile because of conference calls sucking up all your plan minutes, then it might be worth it. Especially worth it if it means you never miss a meeting again.
