People using Google to get to websites. E.g. people navigating to google to then type facebook into google, and then selecting facebook from the search results. Oh dear god why?!
It's faster and easier... Especially when you don't look at what you're typing, a typo in the address bar usually brings you to a crap ad site, while Google always takes you to teh right page even when you mess up half the word.
My geek hates:
When people right click to copy and paste instead of Ctrl C and Ctrl V.
double clicking on links
having 100 desktop icons
People who confuse RAM with HDD capacity
Also, when you use a keyboard shortcut instead of clicking something with the mouse (for example, bringing up the desktop), and say something like "Woah woah woah, what did you just do".
People who choose a low resolution on an LCD monitor to make things bigger.
On forums, people who decide that they need to use a different colour/font to everyone else. (feeks font I think it is, is far far harder on the eye than the stock one.
People who are clueless about piracy: NO windows genuine advantage will NOT pick up this is cracked, yes you can download all updates, yes don't worry this is a key-less release you don't need a bloody product key.
Fanboys.
People who insist on must having the best of everything and slagging off anything worse/cheaper. Making it look like you have to spend €€€ on something when €€ will do.
Ads before video's on news sites etc.
Ads with sound.
