Does anyone actually understand how to use Twitter?

Twiter is like short text message.For example,if you have website or blog,you will be use twitter to send short message about any latest update from your own website or blogs to followers.It more like our mobile sms.How it work?When you follow other twitter,their will follow you.watch following video: http://www.youtube.com/watch?v=KHAZt-Exuaw http://www.youtube.com/watch?v=4YGp4cWdndc

Twitter is quite simple actually! I don't really like the site and don't use it often but... The whole idea is to update your profile (Tweet) every now and then informing your followers of what you are doing or just tell them whatever you want. So if you were my follower and I put "Just saw an awesome video on youtube!" You would probably say cool or something and send me a message somehow on what the video was or ask for a link. Maybe you would tweet "Check out my new blog: http://YOURBLOG.blogspot.com" And I and some others would probably go visit! Understand?
