Twitter is a wonderful platform to engage, lurk, socialize, read, distribute, share, or otherwise “do something” with ideas and content.
Part of what makes it so useful is its 140 character limit. This requires users to be succinct in each tweet, which in turn has encouraged a bit of ingenuity on the part of the users, often in the form of acronyms and other abbreviations that can make things get confusing in a hurry. In response, we’ve created a list of abbreviations to make sense of all that crazy talk.
