Mistakes. We all make them. But many of us shy away from talking about them. One comms pro took a different view and created a massively popular post last year about making mistakes on Twitter. And now she's gone and written the follow-up...

With the 'first seven mistakes we have to make' post last year I started a club for those of us who have learned the hard way and cocked up on Twitter at some point.
Here are seven more 'mistakes': if you have done more than six of the fourteen you are a VIP member for the 'Twitter pro club'. (Rule 1: talk about Twitter pro club. We're communicators aren't we?!)
If there was a dreadful rumour about you, I'm pretty sure you would not find out from someone you don't know on Twitter who appears to be using text speak. You'd hear about it another way I reckon.
Ignore this advice & you'll be publicly tweeting links about Viagra before you know it.
Poor @HelenReynolds. Imagine you're a successful, clever and glamorous entrepreneur going about her business only to get tweets about dog poo and Twitter meant for @HelReynolds, a Welsh local government employee who wears Primark & is probably too fond of a whisky. Inconvenient.
And look at the marvellous @JohnLewis. He was bombarded with tweets at Christmas that would've cheesed most people off or been an opportunity to sell the handle. Not for this guy. He just answered everyone and showed himself to be a proper dude in doing so.
Check the Twitter handles you tweet people! Give these people a break.
Don't get me wrong, you can do what you want on Twitter. But when a be-suited middle manager selects the hashtag you're in trouble. Be strong.
Point out that while wordiness could work for the top of a Word document agenda, #ITstrategyboardAberystwythWalesJune2014 is nearly longer than a tweet. #ITWales14 would do the job.
See also: when you're not sure what a hashtag is but it seems cool, so you just make one of your sentences a hashtag. #itdoesnotreallywork
For example:
"@newcoffeeshop is splendid and you should all follow for coffee news!"
@Joel_Hughes wrote a classic post ages ago about the volume of your tweet: 'Tweet to volume 11 (homage to Spinal Tap)'. This explains it all.
12. Instagram/other app to Twitter bad translation
This one does my swede in. You craft your post on Instagram, add the name of someone and hit the button to publish it to Twitter too. The the tweet comes out all mangled: your last word was chopped out to make space for the link and the Twitter handle you added is lost. With Twitter displaying images in the timeline now you're probably better off just saving the picture and tweeting from your Twitter app.
I once tried tweeting links to a council budget on Pinterest - it was rubbish. Wrong audience, wrong topic, wrong wrong wrong in a hundred ways. Mistake 13 is similar to number 12 but the point is more general.
I don't have enough room to talk about how much I love @GaryVee but one of my favourite things he talks about is making sure you create appropriate content for your audience.
You wouldn't tell the same story in the same way to your boss in a boardroom as you would to your mate in the pub.
So don't autotweet all your Facebook stuff! Different room, different audience! The same goes for all your content - your long wordy blog post is not going to cut it with the Tumblr crowd. It's easier to post the same thing everywhere but it's also putting people off - don't do it.
14. Telling people what to do on Twitter
It's annoying. I break this all the time, and I'm doing it now! At least I'm self-aware.
Debate but be polite and remember we all do stuff our own way. Sometimes it's disheartening for Twitter newbies to be told off for bad etiquette. Keep the lectures for university.
That's your lot.
The fact I'm breaking these rules as I write them is my way of saying I think you should make mistakes, do what you want and don't assume one person's opinion on what is right or wrong is gospel.
You may of course dispute that any of these things are mistakes at all. Give me a shout, I'm happy to be persuaded otherwise!
