Every time I read /. I remember why I don't read /.
The review of Learning Perl has the same responses that every other mention of Perl gets. Don't those kids ever get tired of talking about things they say they don't like and will never use?
Another large segment of responses complain about Perl 6, but in the same fashion as the complaints about Perl 5.
The most surprising posts I've seen (on /. or anywhere) complain that the new edition is insufficiently different from the previous one. Um, well, gees, didn't you learn Perl from your previous edition? It's not a new book, it's a new edition, and if you bought the last edition, you're not in our target audience.
One /. kiddie calls the new edition a "cynical marketing ploy" because we haven't changed much from the third edition. I'm not sure why that's so important to people. I'm amazed that the decisions I made about various things, such as which chapter to use for the free sample, are attributed to O'Reilly malice. There's a lot of hate in those /. posters.
But I know that Slashcode is Perl, and /. is a marketing trap itself. All those kiddies don't even realize that /. is there to make money off their eyeballs while they complain about how they don't like anything. That's right, do that all you like. Just keep looking at the ads and premium content.
