I use Twitter as @jackvinson, and I have found it a great way to keep up with family, friends, colleagues and acquaintances. We let each other know what is happening, we ask each other questions and occasionally provide inspirational guidance.
I tweet about a wide range of things, though the focus is on knowledge management, theory of constraints, personal effectiveness, and what is happening with my family. For a while I was writing about product management too. These are all regular topics on this blog as well - excepting the family stuff. Feel free to check for more details about me on my About page.
If you are curious, the technology I use for Twittering depends on where I am. On my computer (MacBook), I have tried a number of Twitter clients. And sometimes I use the Twitter page itself. As of 2013, I have been primarily using Tweetbot. Tweetbot also has a decent mobile app that I've been using on my iPhone / iPad.
Please feel free to follow me. If I don't follow you, it's probably because I don't know who you are and your Twitter profile doesn't provide me any clue. Please, fix that. At the very least, shoot me an @jackvinson message in Twitter to let me know what interests you.
Many thanks to Doug Cornelius for suggesting this kind of page.
