I've only recently moved away from 4chan's /b/. Having used it for over 3 years I finally grew tired of stupid memes repeated over and over again. Plus the massive influx of trolls and newfags have ruined it completely.
However, the kind of people using internet slang in real life are exactly the people /b/ originally hated (and mostly still does). The reasons can be compared to hating weeaboos (which is now often misinterpreted to liking anything Japanese).
