First, I won't be online today taking Q&A, but I appreciate all feedback, and will check back as time permits.
To answer your first question, it probably means you have more sense than the rest of us, and have better ways to spend your time. ... Seriously, having or not having a Twitter account is not a major deal, unless you work in a role which would seem to require that you have one.
On the other hand, I recommend that everyone create a LinkedIn profile, regardless of whther you are looking for a job. Such an account enables you to stay in touch with former coworkers, and also allows you to build up a list of online references so that you don't have to spend a lot of energy trying to track people down when you ARE considering a job move. Also, when the time comes that you are looking, you have a network of people who know you who might be able to suggest good opportunities to consider.
Good question! Hope that helps...
