Ok, just a quick lesson for everybody.
tHiS iS tOgGLecAse = this togglecase
t|-|15 i$ l3e+ $peA|< = this is leet speak
Please learn and know the difference - they are not the same thing. Granted, many people might find both irritating to read!
I'm not going to give a history lecture about the development of the internet and hacking. I'll spare you.

I'll just say that leet speak is more "culture bound" to the internet than togglecase. As many have pointed out, typing togglecase reminds everyone of an immature 13 year old. If you lump leet speak into that same perception, then you don't know what being leet (l33t) is about. To some folks, it's almost like having a whole other culture and language.
I don't type in toggle or leet myself - I didn't then and I don't now. I have a leet signature line because I'm taking the piss out of one of my old co-workers. Two years after I last saw him, I ran into him at Del Taco, of all places, and we had a great chat. He and I always got along because we were both old school computer kids. (I'm soooooo old school that I was around when l33t was actually 31337!!!!! ) Anyway, he e-mailed me the next day typing in l33t. heh. So, I just wrote my signature to be amusing.
Anyway, other than my colleague's recent e-mails, I can't remember the last time some typed in toggle or leet! Everyone is acting as if this still happens all the time. Can someone tell me if this is more a an occurance in IMs? I don't do the IM thing, so I wouldn't know.
One last thing, all of you who picked up the fad on writing "the" as "teh" (as in "teh pills! They work!")...... "teh" is technically l33t speak.

Good thing i 4|\/| teh Ch1x012 and I had that in my sig line before it became the lastest GC fad.
asdf!!
