I read some introductory materials:
- Basic Introductions: A beginners guide; Twitter in plain English; NY Times
 - More comprehensive overviews: My favourite is The Complete Guide to Twitter. Others include A wiki on Twitter; List of Free ebooks on Twitter;
 - Using twitter as a complement to blog posting: Problogger
 - Academic applications: Twitter tips for academics
 
- I set up an account on Twitter: http://twitter.com/jeromyanglim
 - I set up a referral from my blog to my twitter account on Twitterfeed.
 - I found a few people to follow: I'd heard about the #rstats tag and recognised a few familiar faces from the R community and various blogs that I follow. I ran some searches using some keywords that interest me and found some more people with interesting tweets.
 - I downloaded a Twitter dekstop client called Twhirl.
 - Once I was following a few people, I used Twubble to get other suggestions. It works on the idea that you may want to follow people that are followed by multiple people that you follow.
 - I installed a Twitter App for my iPhone (Twitterrific).
 - FriendOrFollow tells you about who is reciprocating following.
 - I added an option in Feedburner to add a Tweet button to my RSS feeds (introduction to retweeting; retweet button in blogs).
 
Hashtags that interest me
- #rstats ; used to refer to R
 
Assorted ideas for using Twitter that interest me
- Subjects can have a dedicated Twitter hashtag and students can then use this to discuss the subject on Twitter.
 - The main newspaper I read, The Age, has hashtags associated with many of its articles. This makes it possible to write a blog post, make a comment on Twitter that links the article's hashtag to my blog post, and thereby allow readers interested in the article to read my blog post. Here's an example.
 - I am exploring the idea of having multiple accounts for different purposes.
 - Getting answers and feedback on blog posts or anything else.
 - Providing a record of journal articles that I'm reading and sharing key findings. In particular, Twitter can function as a simple recommendation system for increasing exposure to useful materials.
