Here's how it works: a limited number of brands (up to ten) looking to engage with the social media community can have their latest Tweets syndicated into your WordPress blog's sidebar, and interested visitors can choose to connect with those brands on Twitter. You can find out more about how the ad unit looks here or looking in the Mashable sidebar.

The TwitterBrandSponsors plugin has a simple admin interface and includes options for display text, tweet caching and hiding reply tweets. The order of sponsors is randomly rotated for balance.

The plugin's settings page also features weekly and overall click counts on the outgoing links for each TwitterBrandSponsor.
