Hi there, Teeliners :o) Allow me to introduce myself. My name is Grant Ito, in Vancouver Canada. I've had an interest in shorthand since I was young when I found an old book of my brother's called "Instant Shorthand" by John Farrow. A cursory Google search turned up nothing for me when last I tried (a few years back).
I had the opportunity to learn Pitman when I was in high school, and I've regretted not taking it at that time. Since then, I've tried to learn Gregg. I'm not a journalist or court reporter; I'm interested simply for interest's sake.
I love Gregg: I love its cursive look, I love that it includes vowels, I love that it doesn't rely on the thickness of the strokes, I love that it doesn't rely on position relative the line of writing (for the most part)... I don't love the textbook I've been learning it from ("Gregg Simplified") for the simple reason that it doesn't have the transcriptions of the exercises, so I get stuck from time to time.
Enter Teeline: the Teeline Gold textbook has all the transcriptions for the exercises, and it's relatively quick and easy to learn (I've been focussing on getting the written form right, I haven't been working on speed).
On the minus side, I have to confess that I don't like it for its angular look and its "versatility" (e.g., you can choose to write BC or BAC to mean "back") although that's often thought to be a bonus. I've found that the text book, the dictionary, and the phrasebook must have been published at different times because there are discrepancies between them. Still, it's a good system for simple note-taking for me.
There was quite an active Teeline group on Facebook, but I haven't been on Facebook for several months now, so I'm looking for other places where I can both share and can ask questions.
