Basically, whether you're an individual or a company you can have an account and get your news out to those interested. So you try to get as many followers as you can (those are the people who see what you write) and follow those you want to listen to (and those are the messages [tweets] that you see when you log in).
As tilers you can follow us, tta, adhesive firms, and each other. And you want to tweet with those in mind, but your main reason would be to try and attract business or potential customers.
So it wouldn't work on it's own, you'd need to advertise the fact you have twitter on your website or business cards perhaps (website more so to be honest) and then should the customer you've just visited wish to dig around a bit on you, they can see what you've tweeted and perhaps get a bit of a better opinion on your knowledge or whatever.
There are loads of ways companies use it, but you have to think about either using it to find better deals or more training or anything that will improve your business and/or potential customers.
Checkout what others tweet and you'll see what's going on.
I mainly use it to cross-promote the forums and to generally get tradesmen on twitter! lol - see, I'm thinking of you! - those who get the edge now will have a bit of an advantage in the future.
