Twitter etiquette

Twitter is becoming incredibly popular (I'm already addicted), but there are some rules - an etiquette, if you will - for using the micro-blogging service.

'Rules' of Twitter etiquette

So, here's a basic starter for my Twitter etiquette:

1. Don't worry/moan/bitch if someone doesn't reply to an @reply: it's really easy to miss this in the timestream!
2. Try not to flood Twitter with more than 2 (or so) posts in quick succession - you'll look like an attention-seeker.On the other hand, don't leave it weeks between posts - try and post daily! Else you may as well use your blog.
3. Post links. Interesting links. Preferably post them with a brief description - e.g. 'Blog post - Twitter etiquette'. Without the description, they're as bad as spam.
4. If you're posting a long link, try using TinyURL to shorten the address.
5. Follow people, even if you don't know them.
6. Don't cross-post: if you've got lots of Twitter accounts, don't post the same tweets to them - people following more than one of your accounts will get incredibly irritated!
7. If you're posting a tweet you've read from someone else, retweet it: add 'RT' in front of your message, as follows:

   RT @cole007 alf garnett 2.0 mashup for those that missed it: http://www.bnpnearme.co.uk

8. It's fine to ask Twitter rather than just search Google (most of the time) - especially if you know you're being lazy (e.g., addressing your followers 'dear lazyweb'). Just don't abuse it.
9. You're welcome to your privacy: feel free to protect your feeds (but we'll think it's weird if you do). It just seems...against the nature of Twitter, that's all.
10. Bitch about clients if you must, but remember they might see what you say. (You know who you are).

Twitter etiquette - no one is perfect

I'm not claiming to be perfect: I probably ignore a few of these at times (especially number 2)! This post is just an observation of what I've discovered as an avid user of Twitter.

So, what's your Twitter etiquette? Have I missed something incredibly obvious?
