HL Twitter lets you display your tweets as a widget in your sidebar or even browse your entire Twitter history right on your blog. But it also does a whole lot more. You can track multiple Twitter accounts and store all of the tweets on your blog indefinitely (currently Twitter only keep your 3,200 most recent tweets) as well as pulling in any tweets that you reply to for future reference. You can then tweet from your Dashboard or have HL Twitter automatically tweet your new posts with a customisable message.

HL Twitter stores tweets from multiple accounts and displays them via widget, archives and shortcodes as well as auto-tweeting new posts.

I have been using Evergreen Post Tweeter for the past 3 weeks and it has been great. I ran into ZERO problems with it. 
Here is a video review on the plugin and its usage https://www.youtube.com/watch?v=iu3SnpNaMDI
If I had a wishlist it would be able to:
- Have multiple tweets per post, specified in the post
- Have multiple beginning text that randomly rotates
Those 2 things would make the plugin the best, and would make everything look manual.



Works as advertised, best in class...
