My status


More and more I use Twitter to exchange direct messages (DMs) with followers. For you to DM me we need to follow each other first. I do not automatically follow back, so make sure to send me an @reply first to make sure I'll return the follow.  I'm 'aadjemonkeyrock' at Twitter.

I maintain a pretty liberal policy when accepting LinkedIn connection requests, although I do appreciate a personalized message, showing your keen interest to connect.
