As it says above, TwitBoxSL is an object which enables one to post to and receive updates from Twitter, when inside Second Life. If you are not familiar with either of those I might suggest, sir or madam, that you click the previous links to further educate yourself.
What would one use it for? All sorts of random chatterings and such, but I myself find it particularly useful for marking the positions of interesting things that I find on the Grid, due to its particularly easy method of marking a SLURL for one's current location. Explorers may find this handy - I might mention here the Not Possible IRL group as an example.
Please do read the full instruction page....
