Nothing disgusts me quite like watching a sixteen-seventeen-eighteen year old person completely forego the use of capitalisation, punctuation, or other basic grammatical necessities in any one of the following situations:
1) Posting feedback to the administration of a website [A side note: in case you haven't heard, Livejournal staff intends to implement limits on the number of times users can post per day. Hopefully that'll help with the load the servers have been experiencing - but you can imagine the flame war going on. Much bitching from free users about "corporate bullshit" and "unfair treatment", which I won't go into at the moment. Bitching as well from paid users about "I paid for unlimited posting" - which is not actually in the agreement of what a paid account has in any case.]
2) Engaging in roleplay.
3) Attempting to be Taken Seriously at any time.
That said, I've just lost two very long battles in a row on Ansible, and I'm going to bed. So tired....
