Following lots of people and not one single update. Why do people do this? If you want to be interested in my life... have a bit of a life yourself, if you don't mind, ta everso. I don't want to be followed by a service or website unless I followed you first or signed myself up to be added. I'd really like just a tiny sliver of control over my online life. Yes, I know it's not massively realistic to want that... but... where's the twitter-etiquette (good grief, I nearly invented a hideous word then: "twetiquette", but stopped myself just in time!) when you need it???
Why also, do they follow you and then protect their updates?

You get a message saying so an' so is following you. You think... oh, that's nice... I'll go see their profile and see if I should be following them. But oooooh no. You can't. Protected updates only. What *is* that about? If you're following people who don't know you... why are your updates protected? Don't you want to let me see just a tiny bit about you? Okay, so you may be new to Twitter... I accept that. But for those of you who aren't... que???
So, my Twetiquette list*
1. Fill in your profile - I don't want loads, I just want to see a tiny smidge of the real you which would help me decide whether or not following you is a good idea

2. Picture please - it doesn't have to be anything much, but I do like to see that I'm talking to a someone or something
3. Don't protect your updates - Twitter is social... it's not a private club. I know it looks like a nice privacy feature, but if you're to get the most out of Twitter you've got to make connections and protecting your updates, hiding your status, is another Twitter-turn-off
4. Participate don't just aggregate - I'm sure no-one minds the odd bit of blog promotion or Blip-ping... but actively participating with a few thoughts of your own sure makes for a more interesting Twitter
5. Update don't stagnate - a few updates here or there... that's not too much to ask, is it?
6. Learn the importance of @ and 'd' - if it's one-on-one communication you're after, direct messages (d + twittername) are much better than clogging someone's stream with personal communication. If you want to make a comment which'll get noticed by someone else, but which isn't private / exclusive... then an @ reply is the daddy.
7. Retweet selectively - yes, I may have missed someone else's tweet or not be following them and find their message really useful... but use the retweet (RT) facility too often and I start to wonder what you've got to say of your own. Think before you retweet.
Am sure there are more... but those are my main rants converted into a handy little list. Ta da!
* see what I did there - said I wasn't going to use that word and then did - shame on me!
