If you want a crossover of interests that seems weird to some other people but perfectly normal to me, take a bunch of tabletop RPG players, some board gamers, some Civilization players (board and computer games), toss in several collections of science fiction and fantasy books and memorabilia, a small Star Trek club, and then realize that all of these people belong to the same branch of the Society for Creative Anachronism, and you end up with a group in which women made up the majority of the numbers, both in the larger group and in the smaller sub-groups. And back then, "cosplay" was not a word, or at least not one any of us had ever heard.
Or at least that's how it was for me in the decade following TNG's premiere. The way I explained it to people was that "We like science fiction, fantasy, history, computers, and doing things as traditionally as possible... we're just a group of people who can't make up our minds which century we want to live in."
I own the first 12 Star Wars action figures, as well as the TMP figures and most of the first 6" TOS figures. I never got into collecting kits or ships; books have always been my thing. I have a friend in Calgary who has duplicates of some of the large TNG figures... as she put it, "One set to keep in the box and another set to play with." So she's had Beverly Crusher sitting on Picard's lap on her computer desk for years, now, while their counterparts are still in their unopened boxes.
I don't collect many action figures anymore - they got too expensive and it was difficult to find a place to put them anyway. I think the last one I bought was Lily, from First Contact, and I've got Quark and Chief O'Brien around somewhere.
As for other stuff... I've got a ThinkGeek account, and have a few things on my "someday, if the exchange rate ever improves, if I've got the money, and if it's on sale, just maybe..." list. For the most part I prefer the more practical things. The TARDIS blanket they sell is really very cozy in the winter months. As for the fun stuff, I've got the plush Jupiter and Pluto, and it looks like they didn't sell well enough to offer the rest of the solar system.
It just depends on what gets offered. All the t-shirts in the world won't mean a thing if they're not offered in sizes that non-average people need, and there are some items I want but they're not available for Canadian customers.
Do we have transparent aluminum yet?
Thank you for clarifying. The title meant nothing to me because I just don't remember the titles of most Trek episodes other than the TOS/TAS ones, and some of the first-season TNG episodes, though I may have seen the episode itself several times.
We have Gorilla Glass 7 or something. XD
