I've used Twitter through SMS, GPRS, instant message (while it worked), the Web interface and a variety of AIR apps and browser extensions. It's always on, along with my Gmail and work email, and I manage to keep an eye on it without losing too much time. I love the fact that I can use Twitter on my phone (which has a QWERTY keyboard, blessed be), and I do use it a lot on the go.
SNR on Twitter is quite within your control, based on whom you choose to follow. The longer that list, the more the noise will be. Also, the definition of noise bears revisiting on a medium such as Twitter. It's like a thought-stream with far less filtering than an email or a blog, and the baseline level of redundant or useless content is bound to be much higher. What is equally important to note is that it is an extremely responsive almost-real-time knowledge-sharing environment. You just have to ask the right questions (based on who your audience is). It is also extremely viral - your answer may come from complete strangers. On the subject of blogging, it is quite easy to toss out a tweet with a link and be done, but it also lets you think a bit more about what you're blogging. Oh, and it doesn't hurt as a publicity tool for your blog, either. And then there's all the stuff you can do as a business on Twitter. Google is your friend. -- Sumant Srivathsan http://sumants.blogspot.com
