These are all the online applications I am used to. My No.1 favourite is face book as it enables users to communicate with friends through chat or the games provided there.
Despite this not being my first blog, making and writing one is a bit clashing as I am not used to writing blogs but I do think writing blogs is usefull especially in a school like SST where the teachers can ask students to make blogs about what they have learned to see whether they have learned anything.
