We will be doing a Webinar in March on GTD Connect called "Productive Use of Social Media" that will look into this whole issue further.
We will be posting registration for it this week on the home page of Connect.
For those of you that are not GTD Connect members, you can still register as a free trial member (as long as you are a trial or regular member when the Webinar occurs.)
You can also join Connect for just a month for $48, then cancel before the next renewal. We don't make canceling difficult, honestly. It's as simple as sending us an email (firstname.lastname@example.org) or calling us (805-646-8432) one business day before your renewal billing date to cancel.
