Grammar- Why it's important. (Pop reel!)

ogm i egrii tew tihs dfntly.
I do admit I'm a Grammar Nazi, and it peeves me off when people make long, run-on sentences that you cant even read. Especially in games where you have to read something fast, or type stuff, like Cleverbot. +1 from me, and congratulations on pop. reel.

literally* :D

On the internet, I usually use good grammar and spelling, but sometimes I just get lazy and talk like this:

When I'm lazy, I leave out fullstops (periods for you 'muricans. Why would you even call it that? Seriously...) only if my comment is just one sentence and commas but I just always have to capitalise. I cannot stand for some reason, talking like this:
on the internet i usually use good grammar and spelling but sometimes i just get lazy and talk like this

And I cannot STAND this:
0n t43 !nt3rn3t ! usu@11y us3 g00d gr@mm@r @nd $p311!ng but $0m3t!m3s ! ju$t g3t l@zy @nd t@lk l!k3 th!$

What is the point of that?
I also hate this:
On th intnet i usual us god grmer + spelin bt sumtim i jus git laz nd tak lik dis

Thoughts?

spell check

Sometimes I feel lazy and don't capitalize my sentences or put periods at the end but I'll do it for this comment. :D

Lets eat grandma! and Lets eat, Grandma. (grammar makes all the difference)
