How Can you Say Anything in 500 Characters?

How can you say anything in just 500 characters? 500 is the limit the all-knowing, all-seeing, all-limiting BLOGGER COMPUTER has put on my precious little blog. Heck, I could only say “blog” 125 times, much less, if I added spaces between each one. I considered doing that-- you know, blogblogblog etc.-- in protest, but that would be self defeating. So I think I'll just voice my opinion here (I bet if you pay extra, they'll give you more space).

I mean, really, what can you say in 500 characters?
