< thinks that is true, a lot of people wouldn't use certain words which they type/write in an actual conversation. < doesn't uses completely different words in <'s case, considering that < is Irish and some of the terms < would use in an everyday conversation might not make any sense to others.
< would never say "that's awesome" in a real life conversation, < would say something like "that's animal", "that's deadly" or maybe even "that's grand" depending on the situation, but < knows that nobody would make sense of that unless they already knew <, so < doesn't actually type those words aside from using "deadly" a few times.
As far as < knows, "deadly" means something that can kill you to others that aren't familiar with the slang and "animal" would just have someone like "what? it's not an animal".
<'s isn't sure why < doesn't type grand, considering that < does say that a lot in real life. Then again, everyone knows what awesome means.
