As Rys brought up the subject of poor English in IM/IRC, try this for a pet hate.
HTML/Rich text email.
[ rant ]
Email was designed to write a message and electronically pass it across to another. I don't need 25kb emails with nice underlined, fancy letters in 32 colours! I just need the information and attachments thanks.
I use GSM to collect my email while travelling (GPRS is a con). I don't really want to download 250kb of email's which are full of junk HTML tags/rich text. Just write it in plain text! I don't need fancy backgrounds, smilies, colours! Just the URL's, attachments and information.
Incredimail is the worst culprit what could be a simple 2kb email is turned into a 55kb bloat!
Even with 1mb connection both at home and work, I still prefer just good ol plain text. Takes a few seconds to download the lot.
Let alone the security risk of HTML in emails.. malicious code.. blah blah.. whine/pout/grumble...
