I am curious about this. which is better Facebook or twitter. i haves used Facebook for the past 10 months, all my mates use it to. but when i go on google there is this feature called "updates" to the left hand side where it says WEB IMAGES VIDEO SHOPPING, etc.. and when i click UPDATES it comes up @dddkdkfjfjf said "iphone 4 alarm not working", what is this about and what exactly is twitter and how does it work, can anyone read your tweets and do they reach a bigger audience than Facebook?
so if you make a tweet does it go on straight to google? cause there are a million tweets every second. and also can anyone see your tweets with them following you. someone said to me twitter is good cause they were goin for the train and missed it and then caught it cause they were on twitter or something… i don't no. how does it all work.

thanks

this is the site am talkn about: http://www.google.co.uk/realtime
if you type anythin into the search bar and search, all that comes up is live tweets.
how does this work?

usually only your follower on twitter can read your tweets. that website is probably a search engine that goes through twitter. I think if you dont want your tweets to be shown to the whole world just adjust the privacy settings. Facebook has same function as twitter, where you can write what ever is on your mind, all your friends and friends of friends can see it.
