Cool question, Bob!It's funny, I was just thinking about this after something xita said at the PBP...which I won't go into...but anyway.
I only got a computer and got online about two years ago, and the very first thing I did online was search for Buffy sites, particularly Willow/Alyson sites. I became a lurker at Little Willow's We Possess Willow Power board...then after "Hush" aired I was so excited about Tara and what had happened with her and Willow that I had to post. I found that I really enjoyed talking to people in this way, and I started looking for other boards...eventually I came across the Watcher's Diary at Buffyguide, and that became my online home for more than a year. (I even met xita there, though she probably doesn't remember. She posted there once or twice, and I recognized her from willtara, where I lurked, and sent her a private message to say hey.)
Anyway, I was known as AlyKat at the Diary, and I developed a reputation as the most zealous defender of Tara and the W/T relationship on the board--matched only by my dear friend Mary-Jane, who is known as morgan there and as tyche here. But eventually I grew tired of always having to be defensive about W/T, and of people saying hurtful things without regard for others' feelings, and of the general atmosphere of cynicism and negativity toward the show and its characters that began to prevail.
Fortunately Mary-Jane had discovered the Kitten, and she suggested I might find a place of refuge here. I took her advice and started lurking...wonder of wonders, here was a place where not only did I not have to defend W/T, but where people actually respected one another and were thoughtful and considerate, and where the show and everyone involved with it were celebrated! After a few weeks of lurkage, I took the plunge and started posting. Now it's the only board I come to.
It was hard to leave the Watcher's Diary, because I was very well-known and popular there, and trust me, that was a brand-new experience in my life. But I'm glad I did, and I'm even more glad to have the Kitten...I would rather be "just another poster" on a board like this, that is positive and uplifting, than be a star on a board where cynicism and meanness reign.
Plus, Amber knows us and loves us. Kitties are the coolest ever.
