If you ever read the comment sections of youtube or digg, you've
probably run across a posting like this:
dud dats totly asum u ar gr8!!!!!!
I know that more and more people are busy texting and chatting in IRC
and ICQ, and talk mode is totally acceptable there because, if you
were to compose grammatical sentences, or to spell out long words, it
would totally ruin the flow of the conversation.
Same goes for in game chatting. Rubbing it in when you totally pwnd
some noob in deathmatch is an appropriate use of talk mode. I'll even
go so far as to admit that talk mode is acceptable on twitter, after
all abbreviations allow you to pack more inane drivel into 140
characters.
A related peeve is the over use of 1337 speak in internet forums. if
you spell elite 1337 or even leet, you loose off of alt.2600:
ITZ TOT41Y 14|\/|3R D00DZ!!!!11!!!
If the last line of text looked like line noise to you, then you know
how annoying it is to read this crap.
Oh, by the way, why is the signal to noise ratio so low on Youtube. I
run into this crap everywhere, but Youtube is the absolute worse
effected site.
