First, Burberry pushed out a twitter card that doubled as a calendar invite to one of its fashion events. It’ll be interesting to see what other brands (product-based) will do with this feature. Check it out here.

Before, people were running into the issue of having to RT the original, while also commenting, and staying within the 140 character count. Check out the Mashable review here.
