Social Media Jargon: What are all these new words and abbreviations?!

On my Twitter page I have listed some of the words and abbreviations associated with Twitter and tweeting. These include:

RT or Retweet – this is when a message is reused and the originator is acknowledged

MT or Modified Tweet – a retweet that has been modified slightly (often to reduce the character count but sometimes to add emphasis)

DM or Direct Message – this is where you can send or receive a private message (providing both parties follow each other)

HT or Hat Tip – to acknowledge finding another person’s tweet or link interesting.
It is only when you start to talk to someone new to social media and see their confused faces as you add what is to them jargon into your conversation. Despite your best efforts to explain Twitter or Pinterest for example it is important to remember that they may have never come across let alone understand some of these new terms.

I recently came across an A-Z ‘Glossary of Blogging that is being developed on Wikipedia and was amazed to find so many entries of blog-related terms. It made me realiz how many new words are being created. What would you add to this list?!
