You have natural talent which becomes exponentially better with training. But a guy who struggles to even find words will be trounced by you 9 times out of 10. Regardless of who is right.
Interestingly those type of people will rarely venture on message boards, because this requires a lot of reading and writing and they would rather spend their time on other pursuits(maybe more visual?). Its interesting to imagine the section of viewpoints that dont even get represented at this level.
I doubt that has much to do with verbal IQ, though. When I was a kid I also had trouble finding words, so I made a lifelong habit of learning them. As a result it made me an excellent writer and reader, but still didn't improve my speaking.
If you're feeling verbally blocked it's probably more likely that your problem is some form of social anxiety. (That was mine.) If you become much more talkative when drunk, for instance, then the problem is inhibition.
You can meet plenty of garrulous people who can talk circles around you, but it doesn't mean they're necessarily bright.
