These people obsessed with spelling and grammar really annoy me. So what if he/she didn't use punctuation? This isn't a written essay, it's an informal forum for general discussions. Yes it was difficult to read, but he never claimed it wouldn't be.

If you don't have anything to say regarding the topic please just don't say anything at all.

Regarding OP's point, I just think everyone has different strategies which they become quickly accustomed to and find it hard to change.
