I stumbled on this via Jym Cheong’s post on the Tweetlah facebook page. Jym asks on 31 Jan 2009 – “Let’s have 1000 Users!” (there were 36 at the time).
Restrict your tweet to 120 characters though as the URL is inserted at the end of the messsage. I don’t like having to include my password in the SMS each time and it’s for sending not receiving SMS’. Otherwise, it’s a boon to Singapore twitterers and looks to be a blog killer. Go try it out at twitter.sg
Update: see Jym’s responses at the twitter.sg blog.
