Here's mine,
www.twitter.com/frankdoorhofI try to be very active online (also on twitter).
Some people will say that you don't need to be because.........
I think that's shortsighted and oldfashioned.
Reality is that most people are connecting online, are surfing the web and are enjoying shorter news and gossip topics.
Twitter is a place were a lot of rubbish is posted but some people are making a difference and that group is growing.
The attraction for me is that you don't have to type a lot, but you can make short and in that way quick posts to draw attention to your work.
I try to twitter about :
The work we are doing at the moment, backstage videos and photos (shot with the iPhone in realtime), finished work and of course blogposts when I post them.
I've seen a boost on my blog of over 500% since I've been using twitter, but also my website and portfolio got much more hits.
When posting that you twitter on some sites you will get a response that twitter is for people without work who have time, with me it's the opposite, I sometimes really don't know where to find time, however twitter is done in between sessions, in a few free minutes or whatever (it's that quick). The people saying this however are often claiming they are rather free at the moment and have time for sessions for free work.
My opinion is that if you still think the phone will ring you are going to be out of a job in a few years.
The first week I got on Twitter I got two assignments due to my presence there including shooting a band from Norway which I normally would have never known.
The web is here to stay and will in the future be our MAIN form of conversation, advertising and networking, people not jumping on will be left behind and will loose eventually all connections to the market.
Look at products like the Blackberry, iPad, iPhone etc. 5 years ago my mobile phone was used for making telephone calls and receiving them, at the moment my contact with clients is over Twitter, MSN, Mail or other forms of digital means, it works way faster and you can immediately show results/ideas/moodboards etc.
IF twitter will be there in 2-3-4 years I don't know, just like myspace it will probably be replaced by Twitter 2.0 or something else but the way of communicating is changing VERY rapidly, and I strongly believe it's a matter of getting on board or drown.
Good examples are people like Chase Jarvis who thanks to his online presence has made his succes.
