I love the new social networking sites-Facebook.com, Mysapce.com, Change.com, and Linkedin.com.
Twitter is very popular too, and is one of the fastest growing social networking sites.
Twitter has space to write a message that includes 140 characters.
As a Librarian of the 21st century, I want to be where the modern technology is, at the Library 2.0 level.
On another hand, I am worry about E-Generation's information literacy. The 140 characters' writing space reduces the exercise in writing to a concise form filled with symbols and abbreviations. The smallest school paper includes a minimum of 100 to 500 words. The young adults have serious problems with grammar, punctuation, and vocabulary development. The short remarks such as "I am laughing" or "I am clapping" have a regression effect. To be anthropologically correct, it will shrink the brain from the size of a dinosaur to the size of the lizard.
No arguments, it is a good formula or an instrumental tool for building a community of friends and supporters of any online community or organization of people who share the same interests and activities.
After all, I made the point by using almost 140 characters.
