Pet Peeves

I am just one bitter person.

Slow drivers in the left lane

I road rage because of people like this. Stop slowing down traffic!
Defensive WPRs

It's annoying to see WPRs with rules and warnings, saying that reviewees can't write negative things about their review. You cannot govern what they do after you review them. Plus, if you give critiques, learn to receive critiques. Instead of complaining that they broke your ridiculous rules, learn from it and improve.
People who don't look behind them when they back out of a parking spot

I've had several near hits and an actual hit because of this.
People who think they write good HTML/CSS just because it validates

Validation checks syntax. It does not check semantics, which means it can't tell if your code is efficient or in good style. Also, validation does not, I repeat does not, guarantee browser compatibility.
Obsessive iPhone owners

No, I don't care about the latest app you downloaded. Please stop browsing the internet or texting when I'm trying to talk to you. Just put that thing away for once.
Decorated page titles

I hate seeing page titles with random capitalization, version names/numbers, or random symbols. It looks like crap when I look at my browser tabs, and it gives a poor impression of your site when it shows up on search engines.
Mouse cursors that don't change when I hover over a link

You should not force your mouse to stay as the default cursor on hover. A changing cursor is the most prominent and intuitive way for your visitor to tell if something is a link, especially if it's an image link. It should never be a guessing game.
Text that doesn't contrast enough with the background

I wish people would check their text and background with a color analyzer more often. My eyes would be a lot happier.
People who claim they're "old" when they're obviously not

"Omg, I just graduated from high school! I'm so old!" I know it's in jest, but seriously? Man, that must mean I'm ancient since I've graduated from college, am working full time, and am completely independent of my parents' money.
Guitar Hero braggers who don't play on Expert

Medium and Hard are a joke. Perfect yourself on Expert before trying to show off YouTube videos of yourself playing.
Cosplayers who refuse to use wigs

The same amount of effort should be spent on the hair as the rest of the costume. If your natural hair does not resemble the character's, get a wig! Wigs are a practical solution instead of cutting and styling your hair or dyeing it crazy colors each time.
People who think Javascript is bad

It's not. Sure, it's bad when web newbies overdo it with random and useless Javascripts, but when used properly and for functional reasons, it can be very useful.
People who think they know PHP when they've only used includes

Do you know how to write a PHP function? Do you know what PHP variables are? Includes are barely anything!
Complaints on lack of comments

It's annoying when sites or blogs complain that they don't get enough comments. That should not be the driving motivation for owning your site. If you write about nothing of interest to the visitor, they shouldn't have to BS a comment just for the sake of commenting.
