@Redticket: Knowing full well that your article was a commercial plug, I went ahead and read, 'cause I'm an open-minded guy.
You really need to say more about the specifics of your trike, and what it is about the trike that you find enjoyable: different (how?) center of gravity, turning radius, relative stability at speed? At a crawl? How does it do on crappy pavement? Why?
What kind of seats are available, what do they buy you in terms of comfort and security?
I switched to recumbent bicycles from diamond frame bikes about 12 years ago. In exchange for a substantial price penalty, I gained relief from nerve trauma in my hands and crotch, and relief from the perpetual stiff neck brought on by the drop bars on my DF triathlon bike.
I've ridden a number of different recumbent bike geometries: long wheel-base, short wheel-base single, and a short wheel-base tandem. They're all scary the first time you climb a hill on one, because they balance and steer differently from a diamond frame bike.
For someone making their first transition to a recumbent, a trike might be an ideal choice, because you can climb as slow as you need to, without fear of falling over into traffic.
A number of middle aged people I've met have tried recumbent bikes, and spoken highly of a final transition to a trike, despite the added weight and cost of the trikes, for comparable componentry.
The one frustrating experience I've seen a triker endure, was having to drag his "delta" trike up a wet hill, because there wasn't enough weight on the single driven wheel of the rear pair, to provide traction to climb the hill. A "tadpole" trike would probably have done fine.
You need to flesh out your article with specifics. A broad, unqualified statement that "it's fun", isn't likely to open wallets.
Good luck!
