Hey there,
Sending a tweet never quite changed, per se, but the authentication
needs surrounding it did change. This is why I point people to the
example Django application; Twitter requires almost all authentication
to happen over OAuth, which is largely web based (and somewhat
annoying).
The correct method is still updateStatus(), but you need to be
authenticated prior to that and have the correct tokens stored. I took
the example out to try and avoid confusion around this - you can no
longer supply a username/password.
Thanks,
- Ryan
