Ah, yes, Magic. Surely brings back a lot of memories. I remember a time when I read MaRo's articles every week (because I was bored, yes, but I did it). It's kind of fun to see being quoted on someone else's article.
I'm a Johnny all the way, with perhaps a splattering of Timmy. These profiles are very interesting, specially because of how they turn out to be true. I remember back when I began, when I was way more Timmy, playing a friend who was a complete Spike. I was playing an insect time which I had created by looking at all of the insect cards, choosing the coolest ones, and adding land; it had about as much synergy as a jetpack powered by bricks. It was black-green because most cool insects were black or green. So at a point I play Nantuko Shade (for the uninitiated, a creature that gets bigger when you pay black mana). My friend just flips out, going on and on about how you should only use him on an all-black deck. I try to explain why he's on the deck in various ways - I say he's a 'special guest', I say it's a deck just for fun, I even explain my amazing deckbuilding strategy to him - to no avail. He just kept yelling at me, (well, typing in caps) about how that was not how you did it. Who's to say? Just so you know that profiles sometimes not only like different things, but can't even understand the others' existence. Hence why so many cards are labeled bad because the Spikes who write most fansites don't get it.
There's certainly some ground to the idea that these profiles exist in all games. Spikes sound like the Stop Having Fun Guys [http://tvtropes.org/pmwiki/pmwiki.php/Main/StopHavingFunGuys] of lore,(WARNING TV TROPES LINK WAIT TOO LATE AAAAAA) who think only of winning, look down on people who don't read all FAQs and guides to be the absolute best, and think the only way to properly play the game is the most effective one. Johnnies are the guys who are always trying to find where the level boundaries fail and where the invisible platforms are, who always tries to understand the game's rules at a deeper level so that they can break them, who'll leave their consoles running for days as proof of concept if reverse engineering the source code is completely out of the questions, and who avoid FAQs and guides like the plague and look down on those who depend on them. And Timmies are those who just play for fun, make choices out of what they think would be better or how their character would roleplay, enjoy doing things that look cool even if they aren't effective, and are quite sure anyone who plays the game in any other way just is just boring and doesn't know how to have fun.
Incidentally, if I'm a Johnny in Magic, I'm a Timmy in everything else. I'm sure that every time I choose a skill at a game I'm playing everyone who's ever written a FAQ or run a fansite for it feels a shiver.
Lastly, these profiles always reminded me of Bartle's profiles, the four 'suits' of MMORPGs. It's too bad that they aren't common knowledge about gamers - they answer a lot of questions about how gamers act just by existing.
