Post introductions. They're really unnecessary. If you MUST introduce yourself, tell us about something new, because no one cares how much you love the Yeah Yeah Yeahs or Elliott Smith. Limit yourself to music discussion. Talk about anything! Music, movies, books, people, whatever, just don't be lame. Promote rating communities. It's unanimous, everyone here hates them. Disable comments. It'll get your post deleted. Don't use an lj-cut when posting big or multiple pictures, long entries (reviews, articles, tangeants, etc), or advertisements for stuff you're selling (posting a link to your ebay auction is ok). Get your panties in a twist. INTERNET. Can't reply to comments correctly. Know the difference between "Post a new comment" and "Reply to this." It's less confusing for everyone. Suck at spelling and grammar. Use spell check, you lazy bastards.
