It works, but it took quite a bit of time and troubleshooting to get it working. Here are a couple things I had to do:
1. If embedding within a post, you must not use double-quotes or carriage returns in your shortcode.
2. At first install when I plugged in my API Key and API Secret, it did not take, and the values showed as “1”. After I re-submitted the proper values, they took.
3. I had to set use_curl=1 before it would load any tweets. Prior to that, it was saying no recent tweets.
While this is a great plugin, it’s still pretty rough. I am now struggling to pare down which posts it pulls in, as it appears not to be filtering to specific usernames and hashtags, but instead includes all tweets by one of the given usernames PLUS all tweets using the given hash tags (from any user).
