When pg implements proper hyperlinking that doesn't clutter up my text with an ugly URL, I'll stop using a shortener. I understand the positives and negatives of using a shortener, but the positive impact on readability seems to outweigh the negatives when I'm confronted with an ugly link longer than the text I use to introduce it. Sorry if that offends you.

I should have noted that my link was a PDF, though. My apologies for that oversight.
