I don't consider myself an intellectual, but I do read a fair amount, and I enjoy QI, and (althought the topic isn't about swearing, it's relevant, I feel) when I'm out in public and I see people using profanities as a replacement for verbal punctuation, its not... offensive, but just a little demoralising that I have to share a planet with them.
But then I see myself as somewhere in the centre, a little up the scale from the Sun readers but not a Times reader. For instance I do feel sometimes language can be used pretentiously and unnecessarily, for instance I have a friend who'll not shout 'FIRE!' if he can say 'conflagration' and it , to put an intellectual angle on the event, gets on my tits.
Again slightly off topic, I remember him being asked at a party what a mp3 is by an older, less techy person, and he starts going off about mpeg processing layer level 2, and I overhear and step in and say, 'oh mp3s, they're just music but stored in a computer instead of on a disc.' Now, technically, he was more accurate, but I used language to give the poor guy the small bit of info he wanted without making him want to stab me. Thing is, he's damn close to a genius, especially technically, I just wish he had the ability to, well, scale himself down to interact with regular people.
Its like if I'm in a slightly rough pub, I'll keep the long words to a minimum, as without wishing to appear rude, if you confuse a drunk thick person, they tend to react with not a witty putdown, but a fisty putdown, and its hard to theorize quantum physics without any teeth.
Short version, thick people annoy me, and smart people need to quit showing off.
Oh and when it comes to posting, I do seem to go back and edit myself if I find I've used the same word a few times, and scatter some new ones in, so it doesn't feel like I'm repeating myself.
