1. For me, when I was growing up in the 90's, I watched not Barney, Sesame Street or Teletubies, but Transformers. You could say I wasn't normal, but I don't care. I grew up with epic awesomeness.
2. Toy-wise, it's the fact that they are three toys in one. You get a cool car, plane or animal. The process of transforming is like a puzzle, a rubiks cube if you will. After the whole process is done, you get an action figure with cool weapons. Show-wise, it's a typical boy's show, action, action and more face-melting action. That and they always make some of the characters really memorable for kids.
3. It really depends on the series, while the argument can be made that they all are, some of them are very story-oriented, for example, Animated and Beast Wars. And after all Optimus Prime and Duke weren't every boy's father in the 80's for nothing
4. Well, considering this is a site dedicated to adult Transformers collectors, I'd say it appeals to everyone.
5. Not very often, most people think it's awesome. If they do criticize me, I just shrug it off or ignore it.
6. I do Youtube reviews, and hope to be starting a podcast with a few people, and I keep in contact with some Transformers fans I've met via the internet or in person. Not to mention how many people that I have gotten addicted to Tf's and Gunpla.
7. Honestly, I've seen all kinds of fans, so there is no one type to me, I guess for what they collect, if they have more than ten, chances are, they are addicted.
8. Does PAX count? Tried to go to Cybcon last year, but I had to work. So I can't really give you a straight answer.
9. It's always nice to talk with people who know what you're actually talking about, instead of staring at you with a blank look on their faces. On the other hand, it's fun to put people in their place when they think they know something about the subject. Er... ignore that last part lol
10.If classics and generations is an indication, we have a pretty good relationship. Of course, there will always be haters, but I'm generally happy with the direction it's going in. I mean, anything's better than Armada (let the hate mail commence!

)
11.I prefer to think of them as re-imagining of the original, but each is unique in their own way.
12. I have no problems with any Transformers products, save for the obligatory bad figures in every line (see Blazemaster), but I don't buy them, so I am very happy with the memorabilia.
13. The robot designs. It's always cool to see how the creator designs the characters. Each series has its own distinct look, and that's what I find really cool about Transformers.
14. Build quality and the story. Sure the stories are similar, but how they expand upon it is really cool. The toy designs have only gotten better, compare say, G1 Cyclonus to Classics Cyclonus, the difference is really astounding.
15. Nothing, I'm content to let the creative teams do their thing, they continually do a good job. Even if I don't like it (and I give everything a fair chance), I don't buy/watch, so it doesn't bother me. Sure, I complain sometimes, but that's the beauty of sites like this, we can share our opinions.
I really enjoyed doing this, and I second wanting to see the article when it's finished.
PM me if you need any more answers.
Good luck on the article!
