When I used to be on Twitter (before I deleted my account), for a time I only expressed my present feelings using "Shatners", for example:
"I am happy"
"I am angry"
"I am horrified"
There is LITERALLY no emotion that cannot be portrayed via Shatners. Therefore, I am proud to announce the launch of Shatner.pics, quite possibly the best website on the Internet (ever). Check the FAQ on the homepage for usage details, you can thank me later.
