I joined Twitter as an experiment. My username is rembooks. Next to Facebook it is one of the more popular social media. I have found it works well on my smart phone. (I have a Motorola Atrix android phone.) You are limited to only 140 characters in a post or “tweet” as they are called.
Many tweets also have links to web pages. With an internet capable phone you will be able to read a web page. I have found a browser called Boat that can resize a web page so that it is easy to see.
You can use a PC or a smart phone app (I have been using Tweetcaster as you can temporarily make tweets disappear if they get too “tweety”). I am displaying my recent tweets above so you don’t have to join Twitter. I have been mostly “retweeting” other tweets from other sources like Publishers Weekly. But with this page in place I will do more tweeting of my own such as notifying you when there is a new post.
I have found Twitter to be most helpful when awards and shortlists are announced as someone will be tweeting live at the event.
