Getting tweets that mention a user (and other possibilities)

In general, for the Twitter key in twitter_pull_render(), you can use a Twitter search query with operators as described here:
http://search.twitter.com/operators

The exception is that if the Twitter key starts with @, then it gets the tweets from that user instead of tweets mentioning that user.

A simple workaround to get tweets mentioning a user is to add a space before the @. For example, to get tweets mentioning @drupal, try:

<?php echo twitter_pull_render(' @drupal'); ?>

To get tweets either using #drupal or mentioning @drupal, you could use:

<?php echo twitter_pull_render('#drupal OR @drupal'); ?>

Hope that helps!

Subscribing... very handy info.
