Understanding some of the symbols used on Twitter
@ is used to refer to a person or their post. For example @smith1 would refer to someone who’s twitter username was smith1
RT – Re-Tweet, when you re-send another person’s message and or link to all the people who follow you. Used when you particularly agree with something or think it will be helpful to others.
# (also known as a hashtag) tags an event or key word or group topic e.g. #ukedchat (educational discussion). If you type the # entry within the search box you will find others posting on the same topic or event. This is very helpful for linking up with people who have similar interests or are knowledgeable in specific areas. Further examples include: #ICT, #science, #literacy, #eco education, #thinking skills.

http://(followed by a combination of letters and numbers), if you click on it, it will take you to a website.
d, is a direct message, e.g. d smith1 (there must be a space between the d and username). This will go straight to the named person and will not be visible to others.
The < signs are usually used when replying to something you are RTing (retweeting) so e.g. RT@smith1 found link… < thanks Jane looks great!
