I recently came across a Twitter for Business from the team at Hubspot . This is a great resource for those, like me, who are still dipping their toes into Twitter and trying to figure out if it really is useful for B2B marketers, or whether it's just for blatant self-promoters.
Their take on Twitter is it's much like networking that you would do face to face, it's useful for relationship building and management. I'm a little uncertain about networking in cyber-space, call me shy, but I find it a bit confusing when people I don't know follow me. This may just be good Twitter manners on their part, but I feel the pressure to say something interesting and relevant.
If you're getting started with Twitter, I recommend you download the Twitter for Business document. The first section of is Twitter basics, setting up your profile, etiquette, common terms. The section I found most interesting was on the three common business uses for Twitter
- Marketing
- PR
- Customer Service
However if you are going to follow the advice in this document and use Twitter for Marketing, PR and Customer Service, I have the following additions to make. 
Twitter for PR
The list of Australian media in their links was extremely out of date. Here is a much better list, in no order.
Short URLs
To use Twitter to promote blog posts, events or other web based content, you need to tweet a shorter URL. Here is a list of sites that will create one for you directly from the website you're viewing. This is not comprehensive, just a couple of the more popular ones.
http://www.tweetdeck.com/beta/ Tweetdeck aggregates your Twitter and Facebook streams so you can update from one place. Could be useful, but if you use Facebook for personal updates and Twitter for business, be careful not to mix the two.
As more of a Twitter observer, than active participant, I'm interested to see the experiences of companies using it for business purposes, not just individuals, promoting themselves. I'm still unsure whether Twitter is for everyone. It is certainly a useful tactic, not a strategy in itself, but an element of an overall plan to monitor what is being said about your company, to engage (in a relevant way, not a disruptive way) with customers and the media. But, if you work for one of those companies that has to get legal to approve each piece of communication, then Twitter's probably not for you.
