What is twitterspeak? Well it’s how we communicate on twitter and other social media sites of course:)
The hashtag (#) is simply a way to search. This was designed for twitter and is used as a way to search. So if I were discussing mobile learning in a post I could say #mobilelearning and then anyone searching twitter for mobile learning posts could more easily find mine. Now people are using this on facebook, however, facebook does not currently use these to search but that could be changed in the future.
Another symbol used on twitter is the @ symbol. This is used to refer to someone. So if someone were speaking about me, their post might include @raypastore which would then link to my profile. Again this is being used on facebook but does not actually link to the referenced person.
I hope this helps clear up two of the most common ‘symbols’ used on facebook and twitter and help people understand what they mean and how they are used.
