But I thought they had tons of capital flowing in!

Nice to meet you. I used to write primarily in lower case and often ignored punctuation, because it's faster and easier. I also find less-capitalized-than-normal text easier to read.

I find it fascinating that people who communicate largely through certain media (like SMS, or twitter) have evolved their own independent systems for assigning meaning to capitalization and punctuation. While there is a benefit to having an norms shared by all within a discourse community, it's a shame some people are so fastidious and judgemental when applying their own cultural norms to others.
