Maybe hypocisy is too strong a word, but I had to think of something these things have in common. I didn't feel each was worthy of its own post.
One big reason for people liking Perl is that it's a quick, compact language. Why then is this the only of a gazillion message boards (that I know of) that requires the use of tags for something as simple as a line break? Can't anyone who maintains this board figure out how to add an auto-line-break feature?
Two other things I hear from alot of Perl programmers is how important it is to use strict, and how you shouldn't parse HTML with a regular expressions. Well, thanks to my regex HTML parser, I discovered that someone wasn't strict enough in debugging their HTML. In every section, the source code of the "Offer your reply" links is [Offer your reply] (note the missing semicolon). Though the w3 validator didn't catch that one, it did find 283 other errors in http://perlmonks.com/index.pl.
I guess you could also infer from this post that I pay no mind to my reputation here.
Not that I don't like perlmonks...
