I have started to use my Twitter account over the last few days simply because I'm not carrying my laptop or SLR with me at the moment.
Using a blackberry camera and a little text there's no doubt it can be a powerful tool for me in the future. Rather than spending time on heavy text and post creation, which I will continue on the blog, tweets can be made on the fly (ahem!) which is perfect for observational, 'in the field work' on a job like this.
